- * @description
- *
- * This object provides a utility for producing rich Error messages within
- * Angular. It can be called as follows:
- *
- * var exampleMinErr = minErr('example');
- * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
- *
- * The above creates an instance of minErr in the example namespace. The
- * resulting error will have a namespaced error code of example.one.  The
- * resulting error will replace {0} with the value of foo, and {1} with the
- * value of bar. The object is not restricted in the number of arguments it can
- * take.
- *
- * If fewer arguments are specified than necessary for interpolation, the extra
- * interpolation markers will be preserved in the final string.
- *
- * Since data will be parsed statically during a build step, some restrictions
- * are applied with respect to how minErr instances are created and called.
- * Instances should have names of the form namespaceMinErr for a minErr created
- * using minErr('namespace') . Error codes, namespaces and template strings
- * should all be static strings, not variables or general expressions.
- *
- * @param {string} module The namespace to use for the new minErr instance.
- * @param {function} ErrorConstructor Custom error constructor to be 
instantiated when returning
- *   error from returned function, for cases when a particular type of error 
is useful.
- * @returns {function(code:string, template:string, ...templateArgs): Error}

- * * If no destination is supplied, a copy of the object or array is created.
- * * If a destination is provided, all of its elements (for array) or 
properties (for objects)
- *   are deleted and then all elements/properties from the source are copied 
to it.

- * @param {*} source The source that will be used to make a copy.
- *                   Can be any type, including primitives, `null`, and 
`undefined`.
- * @param {(Object|Array)=} destination Destination into which the source is

- * @element ANY
- * @param {angular.Module} ngApp an optional application
- *   address@hidden angular.module module} name to load.
- * @param {boolean=} ngStrictDi if this attribute is present on the app 
element, the injector will be
- *   created in "strict-di" mode. This means that the application will fail to 
invoke functions which
- *   do not use explicit function annotation (and are thus unsuitable for 
minification), as described
- *   in address@hidden guide/di the Dependency Injection guide}, and useful 
debugging info will assist in
- *   tracking down the root of these bugs.
- *
- * @description
- *
- * Use this directive to **auto-bootstrap** an AngularJS application. The 
`ngApp` directive
- * designates the **root element** of the application and is typically placed 
near the root element
- * of the page - e.g. on the `<body>` or `<html>` tags.
- *
- * Only one AngularJS application can be auto-bootstrapped per HTML document. 
The first `ngApp`
- * found in the document will be used to define the root element to 
auto-bootstrap as an
- * application. To run multiple applications in an HTML document you must 
manually bootstrap them using
- * address@hidden angular.bootstrap} instead. AngularJS applications cannot be 
nested within each other.
- *
- * You can specify an **AngularJS module** to be used as the root module for 
the application.  This
- * module will be loaded into the address@hidden auto.$injector} when the 
application is bootstrapped and
- * should contain the application code needed or have dependencies on other 
modules that will
- * contain the code. See address@hidden angular.module} for more information.
- *
- * In the example below if the `ngApp` directive were not placed on the `html` 
element then the
- * document would not be compiled, the `AppController` would not be 
instantiated and the `{{ a+b }}`
- * would not be resolved to `3`.
- *
- * `ngApp` is the easiest, and most common, way to bootstrap an application.
- *
- <example module="ngAppDemo">
-   <file name="index.html">
-   <div ng-controller="ngAppDemoController">
-     I can add: {{a}} + {{b}} =  {{ a+b }}
-   </div>
-   </file>
-   <file name="script.js">
-   angular.module('ngAppDemo', []).controller('ngAppDemoController', 
function($scope) {
-     $scope.a = 1;
-     $scope.b = 2;
-   });
-   </file>
- </example>
- *
- * Using `ngStrictDi`, you would see something like this:
- *
- <example ng-app-included="true">
-   <file name="index.html">
-   <div ng-app="ngAppStrictDemo" ng-strict-di>
-       <div ng-controller="GoodController1">
-           I can add: {{a}} + {{b}} =  {{ a+b }}

retrieving Angular
-     * modules.
-     * All modules (angular core or 3rd party) that should be available to an 
application must be
-     * registered using this mechanism.

-     * # Module
-     *
-     * A module is a collection of services, directives, controllers, filters, 
and configuration information.
-     * `angular.module` is used to configure the address@hidden auto.$injector 
$injector}.
-     *
-     * ```js
-     * // Create a new module
-     * var myModule = angular.module('myModule', []);
-     *
-     * // register a new service
-     * myModule.value('appName', 'MyCoolApp');
-     *
-     * // configure existing services inside initialization blocks.
-     * myModule.config(['$locationProvider', function($locationProvider) {
-     *   // Configure existing providers
-     *   $locationProvider.hashPrefix('!');
-     * }]);
-     * ```
-     *
-     * Then you can create an injector and load your modules like this:
-     *
-     * ```js
-     * var injector = angular.injector(['ng', 'myModule'])
-     * ```
-     *
-     * However it's more likely that you'll just use

-     * address@hidden angular.bootstrap} to simplify this process for you.

-     * @param {!Array.<string>=} requires If specified then new module is 
being created. If
-     *        unspecified then the module is being retrieved for further

- * @ngdoc function
- * @name angular.element
- * @module ng
- * @kind function
- *
- * @description
- * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) 
element.
- *
- * If jQuery is available, `angular.element` is an alias for the
- * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not 
available, `angular.element`
- * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or 
"jqLite."
- *
- * <div class="alert alert-success">jqLite is a tiny, API-compatible subset of 
jQuery that allows
- * Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** 
implements only the most
- * commonly needed functionality with the goal of having a very small 
footprint.</div>
- *
- * To use jQuery, simply load it before `DOMContentLoaded` event fired.
- *
- * <div class="alert">**Note:** all element references in Angular are always 
wrapped with jQuery or
- * jqLite; they are never raw DOM references.</div>
- *
- * ## Angular's jqLite
- * jqLite provides only the following jQuery methods:
- *
- * - [`addClass()`](http://api.jquery.com/addClass/)
- * - [`after()`](http://api.jquery.com/after/)
- * - [`append()`](http://api.jquery.com/append/)
- * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as 
parameters
- * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, 
selectors or eventData
- * - [`children()`](http://api.jquery.com/children/) - Does not support 
selectors
- * - [`clone()`](http://api.jquery.com/clone/)
- * - [`contents()`](http://api.jquery.com/contents/)
- * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, 
does not call `getComputedStyle()`
- * - [`data()`](http://api.jquery.com/data/)
- * - [`detach()`](http://api.jquery.com/detach/)
- * - [`empty()`](http://api.jquery.com/empty/)
- * - [`eq()`](http://api.jquery.com/eq/)
- * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
- * - [`hasClass()`](http://api.jquery.com/hasClass/)
- * - [`html()`](http://api.jquery.com/html/)
- * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
- * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, 
selectors or eventData
- * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces or 
selectors
- * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or 
selectors
- * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
- * - [`prepend()`](http://api.jquery.com/prepend/)
- * - [`prop()`](http://api.jquery.com/prop/)
- * - [`ready()`](http://api.jquery.com/ready/)
- * - [`remove()`](http://api.jquery.com/remove/)
- * - [`removeAttr()`](http://api.jquery.com/removeAttr/)
- * - [`removeClass()`](http://api.jquery.com/removeClass/)
- * - [`removeData()`](http://api.jquery.com/removeData/)
- * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
- * - [`text()`](http://api.jquery.com/text/)
- * - [`toggleClass()`](http://api.jquery.com/toggleClass/)
- * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a 
dummy event object to handlers.
- * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces
- * - [`val()`](http://api.jquery.com/val/)
- * - [`wrap()`](http://api.jquery.com/wrap/)
- *
- * ## jQuery/jqLite Extras
- * Angular also provides the following additional methods and events to both 
jQuery and jqLite:
- *
- * ### Events
- * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction 
apis and fires this event
- *    on all DOM nodes being removed.  This can be used to clean up any 3rd 
party bindings to the DOM
- *    element before it is removed.
- *
- * ### Methods
- * - `controller(name)` - retrieves the controller of the current element or 
its parent. By default
- *   retrieves controller associated with the `ngController` directive. If 
`name` is provided as
- *   camelCase directive name, then the controller for this directive will be 
retrieved (e.g.
- *   `'ngModel'`).
- * - `injector()` - retrieves the injector of the current element or its 
parent.
- * - `scope()` - retrieves the address@hidden ng.$rootScope.Scope scope} of 
the current
- *   element or its parent. Requires address@hidden 
guide/production#disabling-debug-data Debug Data} to
- *   be enabled.
- * - `isolateScope()` - retrieves an isolate address@hidden 
ng.$rootScope.Scope scope} if one is attached directly to the
- *   current element. This getter should be used only on elements that contain 
a directive which starts a new isolate
- *   scope. Calling `scope()` on this element always returns the original 
non-isolate scope.
- *   Requires address@hidden guide/production#disabling-debug-data Debug Data} 
to be enabled.
- * - `inheritedData()` - same as `data()`, but walks up the DOM until a value 
is found or the top
- *   parent element is reached.
- *
- * @param {string|DOMElement} element HTML string or DOMElement to be wrapped 
into jQuery.
- * @returns {Object} jQuery object.

- *
- * @param {Array.<string|Function>} modules A list of module functions or

- *
- * @example
- * Typical usage
- * ```js
- *   // create an injector
- *   var $injector = angular.injector(['ng']);
- *
- *   // use the injector to kick off your application
- *   // use the type inference to auto inject arguments, or use implicit 
injection

- * ```
- *
- * Sometimes you want to get access to the injector of a currently running 
Angular app
- * from outside Angular. Perhaps, you want to inject and compile some markup 
after the

`injector()` added

- *
- * *This is fairly rare but could be the case if a third party library is 
injecting the
- * markup.*
- *
- * In the following example a new block of HTML containing a `ng-controller`
- * directive is added to the end of the document body by JQuery. We then 
compile and link
- * it into the current AngularJS scope.
- *
- * ```js
- * var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');

-/**
- * @ngdoc service

- *
- * @description
- *
- * `$injector` is used to retrieve object instances as defined by
- * address@hidden auto.$provide provider}, instantiate types, invoke methods,
- * and load modules.
- *
- * The following always holds true:
- *
- * ```js
- *   var $injector = angular.injector();

- *
- * # Injection Function Annotation
- *
- * JavaScript does not have annotations, and annotations are needed for 
dependency injection. The
- * following are all valid ways of annotating function with injection 
arguments and are equivalent.
- *
- * ```js
- *   // inferred (only works if code not minified/obfuscated)
- *   $injector.invoke(function(serviceA){});
- *
- *   // annotated
- *   function explicit(serviceA) {};
- *   explicit.$inject = ['serviceA'];
- *   $injector.invoke(explicit);
- *
- *   // inline
- *   $injector.invoke(['serviceA', function(serviceA){}]);
- * ```
- *
- * ## Inference
- *
- * In JavaScript calling `toString()` on a function returns the function 
definition. The definition
- * can then be parsed and the function arguments can be extracted. This method 
of discovering
- * annotations is disallowed when the injector is in strict mode.
- * *NOTE:* This does not work with minification, and obfuscation tools since 
these tools change the
- * argument names.
- *
- * ## `$inject` Annotation
- * By adding an `$inject` property onto a function the injection parameters 
can be specified.
- *
- * ## Inline
- * As an array of injection names, where the last item in the array is the 
function to call.

-/**
- * @ngdoc method
- * @name $injector#annotate
- *
- * @description
- * Returns an array of service names which the function is requesting for 
injection. This API is
- * used by the injector to determine which services need to be injected into 
the function when the
- * function is invoked. There are three ways in which the function can be 
annotated with the needed
- * dependencies.
- *
- * # Argument names
- *
- * The simplest form is to extract the dependencies from the arguments of the 
function. This is done
- * by converting the function into a string using `toString()` method and 
extracting the argument
- * names.
- * ```js
- *   // Given
- *   function MyController($scope, $route) {
- *     // ...
- *   }
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * You can disallow this method by using strict injection mode.
- *
- * This method does not work with code minification / obfuscation. For this 
reason the following
- * annotation strategies are supported.
- *
- * # The `$inject` property
- *
- * If a function has an `$inject` property and its value is an array of 
strings, then the strings
- * represent names of services to be injected into the function.
- * ```js
- *   // Given
- *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
- *     // ...
- *   }
- *   // Define function dependencies
- *   MyController['$inject'] = ['$scope', '$route'];
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * # The array notation
- *
- * It is often desirable to inline Injected functions and that's when setting 
the `$inject` property
- * is very inconvenient. In these situations using the array notation to 
specify the dependencies in
- * a way that survives minification is a better choice:
- *
- * ```js
- *   // We wish to write this (not minification / obfuscation safe)
- *   injector.invoke(function($compile, $rootScope) {
- *     // ...
- *   });
- *
- *   // We are forced to write break inlining
- *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
- *     // ...
- *   };
- *   tmpFn.$inject = ['$compile', '$rootScope'];
- *   injector.invoke(tmpFn);
- *
- *   // To better support inline function the inline annotation is supported
- *   injector.invoke(['$compile', '$rootScope', function(obfCompile, 
obfRootScope) {
- *     // ...
- *   }]);
- *
- *   // Therefore
- *   expect(injector.annotate(
- *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) 
{}])
- *    ).toEqual(['$compile', '$rootScope']);
- * ```
- *
- * @param {Function|Array.<string|Function>} fn Function for which dependent 
service names need to
- * be retrieved as described above.
- *
- * @param {boolean=} [strictDi=false] Disallow argument name annotation 
inference.

are also exposed on
- * address@hidden angular.Module}.
- *
- * An Angular **service** is a singleton object created by a **service 
factory**.  These **service
- * factories** are functions which, in turn, are created by a **service 
provider**.
- * The **service providers** are constructor functions. When instantiated they 
must contain a
- * property called `$get`, which holds the **service factory** function.
- *
- * When you request a service, the address@hidden auto.$injector $injector} is 
responsible for finding the
- * correct **service provider**, instantiating it and then calling its `$get` 
**service factory**
- * function to get the instance of the **service**.
- *
- * Often services have no configuration options and there is no need to add 
methods to the service
- * provider.  The provider will be no more than a constructor function with a 
`$get` property. For
- * these cases the address@hidden auto.$provide $provide} service has 
additional helper methods to register
- * services without specifying a provider.
- *
- * * address@hidden auto.$provide#provider provider(provider)} - registers a

- *     providers and services.
- * * address@hidden auto.$provide#value value(obj)} - registers a value/object 
that can only be accessed by
- *     services, not providers.
- * * address@hidden auto.$provide#factory factory(fn)} - registers a service 
**factory function**, `fn`,
- *     that will be wrapped in a **service provider** object, whose `$get` 
property will contain the
- *     given factory function.
- * * address@hidden auto.$provide#service service(class)} - registers a 
**constructor function**, `class`
- *     that will be wrapped in a **service provider** object, whose `$get` 
property will instantiate
- *      a new object using the given constructor function.

-   *
-   * Additionally, you can use its address@hidden ng.$anchorScroll#yOffset 
yOffset} property to specify a

-   *

-   * If set, specifies a vertical scroll-offset. This is often useful when

-   *
-   * `yOffset` can be specified in various ways:
-   * - **number**: A fixed number of pixels to be used as offset.<br /><br />
-   * - **function**: A getter function called everytime `$anchorScroll()` is 
executed. Must return
-   *   a number representing the offset (in pixels).<br /><br />
-   * - **jqLite**: A jqLite/jQuery element to be used for specifying the 
offset. The distance from
-   *   the top of the page to the element's bottom will be used as offset.<br 
/>
-   *   **Note**: The element will be taken into account only as long as its 
`position` is set to
-   *   `fixed`. This option is useful, when dealing with responsive 
navbars/headers that adjust
-   *   their height and/or positioning according to the viewport's size.

- *

- *
- * <div class="alert alert-warning">
- * **Note:** This document is an in-depth reference of all directive options.
- * For a gentle introduction to directives with examples of common use cases,
- * see the address@hidden guide/directive directive guide}.
- * </div>
- *
- * ## Comprehensive Directive API
- *
- * There are many different options for a directive.
- *
- * The difference resides in the return value of the factory function.
- * You can either return a "Directive Definition Object" (see below) that 
defines the directive properties,
- * or just the `postLink` function (all other properties will have the default 
values).
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's recommended to use the "directive definition 
object" form.
- * </div>
- *
- * Here's an example directive declared with a Directive Definition Object:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       priority: 0,
- *       template: '<div></div>', // or // function(tElement, tAttrs) { ... },
- *       // or
- *       // templateUrl: 'directive.html', // or // function(tElement, tAttrs) 
{ ... },
- *       transclude: false,
- *       restrict: 'A',
- *       templateNamespace: 'html',
- *       scope: false,
- *       controller: function($scope, $element, $attrs, $transclude, 
otherInjectables) { ... },
- *       controllerAs: 'stringAlias',
- *       require: 'siblingDirectiveName', // or // ['^parentDirectiveName', 
'?optionalDirectiveName', '?^optionalParent'],
- *       compile: function compile(tElement, tAttrs, transclude) {
- *         return {
- *           pre: function preLink(scope, iElement, iAttrs, controller) { ... 
},
- *           post: function postLink(scope, iElement, iAttrs, controller) { 
... }
- *         }
- *         // or
- *         // return function postLink( ... ) { ... }
- *       },
- *       // or
- *       // link: {
- *       //  pre: function preLink(scope, iElement, iAttrs, controller) { ... 
},
- *       //  post: function postLink(scope, iElement, iAttrs, controller) { 
... }
- *       // }
- *       // or
- *       // link: function postLink( ... ) { ... }
- *     };
- *     return directiveDefinitionObject;
- *   });
- * ```
- *
- * <div class="alert alert-warning">
- * **Note:** Any unspecified options will use the default value. You can see 
the default values below.
- * </div>
- *
- * Therefore the above can be simplified as:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       link: function postLink(scope, iElement, iAttrs) { ... }
- *     };
- *     return directiveDefinitionObject;
- *     // or
- *     // return function postLink(scope, iElement, iAttrs) { ... }
- *   });
- * ```
- *
- *
- *
- * ### Directive Definition Object
- *
- * The directive definition object provides instructions to the address@hidden 
ng.$compile
- * compiler}. The attributes are:
- *
- * #### `multiElement`
- * When this property is set to true, the HTML compiler will collect DOM nodes 
between
- * nodes with the attributes `directive-name-start` and `directive-name-end`, 
and group them
- * together as the directive elements. It is recomended that this feature be 
used on directives
- * which are not strictly behavioural (such as address@hidden ngClick}), and 
which
- * do not manipulate or replace child nodes (such as address@hidden 
ngInclude}).
- *
- * #### `priority`
- * When there are multiple directives defined on a single DOM element, 
sometimes it
- * is necessary to specify the order in which the directives are applied. The 
`priority` is used
- * to sort the directives before their `compile` functions get called. 
Priority is defined as a
- * number. Directives with greater numerical `priority` are compiled first. 
Pre-link functions
- * are also run in priority order, but post-link functions are run in reverse 
order. The order
- * of directives with the same priority is undefined. The default priority is 
`0`.
- *
- * #### `terminal`
- * If set to true then the current `priority` will be the last set of 
directives
- * which will execute (any directives at the current priority will still 
execute
- * as the order of execution on same `priority` is undefined). Note that 
expressions
- * and other directives used in the directive's template will also be excluded 
from execution.
- *
- * #### `scope`
- * **If set to `true`,** then a new scope will be created for this directive. 
If multiple directives on the
- * same element request a new scope, only one new scope is created. The new 
scope rule does not
- * apply for the root of the template since the root of the template always 
gets a new scope.
- *
- * **If set to `{}` (object hash),** then a new "isolate" scope is created. 
The 'isolate' scope differs from
- * normal scope in that it does not prototypically inherit from the parent 
scope. This is useful
- * when creating reusable components, which should not accidentally read or 
modify data in the
- * parent scope.
- *
- * The 'isolate' scope takes an object hash which defines a set of local scope 
properties
- * derived from the parent scope. These local properties are useful for 
aliasing values for
- * templates. Locals definition is a hash of local scope property to its 
source:
- *
- * * address@hidden or address@hidden - bind a local scope property to the 
value of DOM attribute. The result is
- *   always a string since DOM attributes are strings. If no `attr` name is 
specified  then the
- *   attribute name is assumed to be the same as the local name.
- *   Given `<widget my-attr="hello {{name}}">` and widget definition
- *   of `scope: { localName:'@myAttr' }`, then widget scope property 
`localName` will reflect
- *   the interpolated value of `hello {{name}}`. As the `name` attribute 
changes so will the
- *   `localName` property on the widget scope. The `name` is read from the 
parent scope (not
- *   component scope).
- *
- * * `=` or `=attr` - set up bi-directional binding between a local scope 
property and the
- *   parent scope property of name defined via the value of the `attr` 
attribute. If no `attr`
- *   name is specified then the attribute name is assumed to be the same as 
the local name.
- *   Given `<widget my-attr="parentModel">` and widget definition of
- *   `scope: { localModel:'=myAttr' }`, then widget scope property 
`localModel` will reflect the
- *   value of `parentModel` on the parent scope. Any changes to `parentModel` 
will be reflected
- *   in `localModel` and any changes in `localModel` will reflect in 
`parentModel`. If the parent
- *   scope property doesn't exist, it will throw a 
NON_ASSIGNABLE_MODEL_EXPRESSION exception. You
- *   can avoid this behavior using `=?` or `=?attr` in order to flag the 
property as optional. If
- *   you want to shallow watch for changes (i.e. $watchCollection instead of 
$watch) you can use
- *   `=*` or `=*attr` (`=*?` or `=*?attr` if the property is optional).
- *
- * * `&` or `&attr` - provides a way to execute an expression in the context 
of the parent scope.
- *   If no `attr` name is specified then the attribute name is assumed to be 
the same as the
- *   local name. Given `<widget my-attr="count = count + value">` and widget 
definition of
- *   `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` 
will point to
- *   a function wrapper for the `count = count + value` expression. Often it's 
desirable to
- *   pass data from the isolated scope via an expression to the parent scope, 
this can be
- *   done by passing a map of local variable names and values into the 
expression wrapper fn.
- *   For example, if the expression is `increment(amount)` then we can specify 
the amount value
- *   by calling the `localFn` as `localFn({amount: 22})`.
- *
- *
- * #### `bindToController`
- * When an isolate scope is used for a component (see above), and 
`controllerAs` is used, `bindToController: true` will
- * allow a component to have its properties bound to the controller, rather 
than to scope. When the controller
- * is instantiated, the initial values of the isolate scope bindings are 
already available.
- *
- * #### `controller`
- * Controller constructor function. The controller is instantiated before the
- * pre-linking phase and it is shared with other directives (see
- * `require` attribute). This allows the directives to communicate with each 
other and augment
- * each other's behavior. The controller is injectable (and supports bracket 
notation) with the following locals:
- *
- * * `$scope` - Current scope associated with the element
- * * `$element` - Current element
- * * `$attrs` - Current attributes object for the element
- * * `$transclude` - A transclude linking function pre-bound to the correct 
transclusion scope:
- *   `function([scope], cloneLinkingFn, futureParentElement)`.
- *    * `scope`: optional argument to override the scope.
- *    * `cloneLinkingFn`: optional argument to create clones of the original 
transcluded content.
- *    * `futureParentElement`:
- *        * defines the parent to which the `cloneLinkingFn` will add the 
cloned elements.
- *        * default: `$element.parent()` resp. `$element` for 
`transclude:'element'` resp. `transclude:true`.
- *        * only needed for transcludes that are allowed to contain non html 
elements (e.g. SVG elements)
- *          and when the `cloneLinkinFn` is passed,
- *          as those elements need to created and cloned in a special way when 
they are defined outside their
- *          usual containers (e.g. like `<svg>`).
- *        * See also the `directive.templateNamespace` property.
- *
- *
- * #### `require`
- * Require another directive and inject its controller as the fourth argument 
to the linking function. The
- * `require` takes a string name (or array of strings) of the directive(s) to 
pass in. If an array is used, the
- * injected argument will be an array in corresponding order. If no such 
directive can be
- * found, or if the directive does not have a controller, then an error is 
raised. The name can be prefixed with:
- *
- * * (no prefix) - Locate the required controller on the current element. 
Throw an error if not found.
- * * `?` - Attempt to locate the required controller or pass `null` to the 
`link` fn if not found.
- * * `^` - Locate the required controller by searching the element and its 
parents. Throw an error if not found.
- * * `^^` - Locate the required controller by searching the element's parents. 
Throw an error if not found.
- * * `?^` - Attempt to locate the required controller by searching the element 
and its parents or pass
- *   `null` to the `link` fn if not found.
- * * `?^^` - Attempt to locate the required controller by searching the 
element's parents, or pass
- *   `null` to the `link` fn if not found.
- *
- *
- * #### `controllerAs`
- * Controller alias at the directive scope. An alias for the controller so it
- * can be referenced at the directive template. The directive needs to define 
a scope for this
- * configuration to be used. Useful in the case when directive is used as 
component.
- *
- *
- * #### `restrict`
- * String of subset of `EACM` which restricts the directive to a specific 
directive
- * declaration style. If omitted, the defaults (elements and attributes) are 
used.
- *
- * * `E` - Element name (default): `<my-directive></my-directive>`
- * * `A` - Attribute (default): `<div my-directive="exp"></div>`
- * * `C` - Class: `<div class="my-directive: exp;"></div>`
- * * `M` - Comment: `<!-- directive: my-directive exp -->`
- *
- *
- * #### `templateNamespace`
- * String representing the document type used by the markup in the template.
- * AngularJS needs this information as those elements need to be created and 
cloned
- * in a special way when they are defined outside their usual containers like 
`<svg>` and `<math>`.
- *
- * * `html` - All root nodes in the template are HTML. Root nodes may also be
- *   top-level elements such as `<svg>` or `<math>`.
- * * `svg` - The root nodes in the template are SVG elements (excluding 
`<math>`).
- * * `math` - The root nodes in the template are MathML elements (excluding 
`<svg>`).
- *
- * If no `templateNamespace` is specified, then the namespace is considered to 
be `html`.
- *
- * #### `template`
- * HTML markup that may:
- * * Replace the contents of the directive's element (default).
- * * Replace the directive's element itself (if `replace` is true - 
DEPRECATED).
- * * Wrap the contents of the directive's element (if `transclude` is true).
- *
- * Value may be:
- *
- * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
- * * A function which takes two arguments `tElement` and `tAttrs` (described 
in the `compile`
- *   function api below) and returns a string value.
- *
- *
- * #### `templateUrl`
- * This is similar to `template` but the template is loaded from the specified 
URL, asynchronously.
- *
- * Because template loading is asynchronous the compiler will suspend 
compilation of directives on that element
- * for later when the template has been resolved.  In the meantime it will 
continue to compile and link
- * sibling and parent elements as though this element had not contained any 
directives.
- *
- * The compiler does not suspend the entire compilation to wait for templates 
to be loaded because this
- * would result in the whole app "stalling" until all templates are loaded 
asynchronously - even in the
- * case when only one deeply nested directive has `templateUrl`.
- *
- * Template loading is asynchronous even if the template has been preloaded 
into the address@hidden $templateCache}
- *
- * You can specify `templateUrl` as a string representing the URL or as a 
function which takes two
- * arguments `tElement` and `tAttrs` (described in the `compile` function api 
below) and returns
- * a string value representing the url.  In either case, the template URL is 
passed through address@hidden
- * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
- *
- *
- * #### `replace` ([*DEPRECATED*!], will be removed in next major release - 
i.e. v2.0)
- * specify what the template should replace. Defaults to `false`.
- *
- * * `true` - the template will replace the directive's element.
- * * `false` - the template will replace the contents of the directive's 
element.
- *
- * The replacement process migrates all of the attributes / classes from the 
old element to the new
- * one. See the address@hidden guide/directive#template-expanding-directive
- * Directives Guide} for an example.
- *
- * There are very few scenarios where element replacement is required for the 
application function,
- * the main one being reusable custom components that are used within SVG 
contexts
- * (because SVG doesn't work with custom elements in the DOM tree).
- *
- * #### `transclude`
- * Extract the contents of the element where the directive appears and make it 
available to the directive.
- * The contents are compiled and provided to the directive as a **transclusion 
function**. See the
- * address@hidden $compile#transclusion Transclusion} section below.
- *
- * There are two kinds of transclusion depending upon whether you want to 
transclude just the contents of the
- * directive's element or the entire element:
- *
- * * `true` - transclude the content (i.e. the child nodes) of the directive's 
element.
- * * `'element'` - transclude the whole of the directive's element including 
any directives on this
- *   element that defined at a lower priority than this directive. When used, 
the `template`
- *   property is ignored.
- *
- *
- * #### `compile`
- *
- * ```js
- *   function compile(tElement, tAttrs, transclude) { ... }
- * ```
- *
- * The compile function deals with transforming the template DOM. Since most 
directives do not do
- * template transformation, it is not used often. The compile function takes 
the following arguments:
- *
- *   * `tElement` - template element - The element where the directive has 
been declared. It is
- *     safe to do template transformation on the element and child elements 
only.
- *
- *   * `tAttrs` - template attributes - Normalized list of attributes declared 
on this element shared
- *     between all directive compile functions.
- *
- *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: 
`function(scope, cloneLinkingFn)`
- *
- * <div class="alert alert-warning">
- * **Note:** The template instance and the link instance may be different 
objects if the template has
- * been cloned. For this reason it is **not** safe to do anything other than 
DOM transformations that
- * apply to all cloned DOM nodes within the compile function. Specifically, 
DOM listener registration
- * should be done in a linking function rather than in a compile function.
- * </div>
-
- * <div class="alert alert-warning">
- * **Note:** The compile function cannot handle directives that recursively 
use themselves in their
- * own templates or compile functions. Compiling these directives results in 
an infinite loop and a
- * stack overflow errors.
- *
- * This can be avoided by manually using $compile in the postLink function to 
imperatively compile
- * a directive's template instead of relying on automatic template compilation 
via `template` or
- * `templateUrl` declaration or manual compilation inside the compile function.
- * </div>
- *
- * <div class="alert alert-error">
- * **Note:** The `transclude` function that is passed to the compile function 
is deprecated, as it
- *   e.g. does not know about the right outer scope. Please use the transclude 
function that is passed
- *   to the link function instead.
- * </div>
-
- * A compile function can have a return value which can be either a function 
or an object.
- *
- * * returning a (post-link) function - is equivalent to registering the 
linking function via the
- *   `link` property of the config object when the compile function is empty.
- *
- * * returning an object with function(s) registered via `pre` and `post` 
properties - allows you to
- *   control when a linking function should be called during the linking 
phase. See info about
- *   pre-linking and post-linking functions below.
- *
- *
- * #### `link`
- * This property is used only if the `compile` property is not defined.
- *
- * ```js
- *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
- * ```
- *
- * The link function is responsible for registering DOM listeners as well as 
updating the DOM. It is
- * executed after the template has been cloned. This is where most of the 
directive logic will be
- * put.
- *
- *   * `scope` - address@hidden ng.$rootScope.Scope Scope} - The scope to be 
used by the
- *     directive for registering address@hidden ng.$rootScope.Scope#$watch 
watches}.
- *
- *   * `iElement` - instance element - The element where the directive is to 
be used. It is safe to
- *     manipulate the children of the element only in `postLink` function 
since the children have
- *     already been linked.
- *
- *   * `iAttrs` - instance attributes - Normalized list of attributes declared 
on this element shared
- *     between all directive linking functions.
- *
- *   * `controller` - a controller instance - A controller instance if at 
least one directive on the
- *     element defines a controller. The controller is shared among all the 
directives, which allows
- *     the directives to use the controllers as a communication channel.
- *
- *   * `transcludeFn` - A transclude linking function pre-bound to the correct 
transclusion scope.
- *     This is the same as the `$transclude`
- *     parameter of directive controllers, see there for details.
- *     `function([scope], cloneLinkingFn, futureParentElement)`.
- *
- * #### Pre-linking function
- *
- * Executed before the child elements are linked. Not safe to do DOM 
transformation since the
- * compiler linking function will fail to locate the correct elements for 
linking.
- *
- * #### Post-linking function
- *
- * Executed after the child elements are linked.
- *
- * Note that child elements that contain `templateUrl` directives will not 
have been compiled
- * and linked since they are waiting for their template to load asynchronously 
and their own
- * compilation and linking has been suspended until that occurs.
- *
- * It is safe to do DOM transformation in the post-linking function on 
elements that are not waiting
- * for their async templates to be resolved.
- *
- *
- * ### Transclusion
- *
- * Transclusion is the process of extracting a collection of DOM element from 
one part of the DOM and
- * copying them to another part of the DOM, while maintaining their connection 
to the original AngularJS
- * scope from where they were taken.
- *
- * Transclusion is used (often with address@hidden ngTransclude}) to insert the
- * original contents of a directive's element into a specified place in the 
template of the directive.
- * The benefit of transclusion, over simply moving the DOM elements manually, 
is that the transcluded
- * content has access to the properties on the scope from which it was taken, 
even if the directive
- * has isolated scope.
- * See the address@hidden 
guide/directive#creating-a-directive-that-wraps-other-elements Directives 
Guide}.
- *
- * This makes it possible for the widget to have private state for its 
template, while the transcluded
- * content has access to its originating scope.
- *
- * <div class="alert alert-warning">
- * **Note:** When testing an element transclude directive you must not place 
the directive at the root of the
- * DOM fragment that is being compiled. See address@hidden 
guide/unit-testing#testing-transclusion-directives
- * Testing Transclusion Directives}.
- * </div>
- *
- * #### Transclusion Functions
- *
- * When a directive requests transclusion, the compiler extracts its contents 
and provides a **transclusion
- * function** to the directive's `link` function and `controller`. This 
transclusion function is a special
- * **linking function** that will return the compiled contents linked to a new 
transclusion scope.
- *
- * <div class="alert alert-info">
- * If you are just using address@hidden ngTransclude} then you don't need to 
worry about this function, since
- * ngTransclude will deal with it for us.
- * </div>
- *
- * If you want to manually control the insertion and removal of the 
transcluded content in your directive
- * then you must use this transclude function. When you call a transclude 
function it returns a a jqLite/JQuery
- * object that contains the compiled DOM, which is linked to the correct 
transclusion scope.
- *
- * When you call a transclusion function you can pass in a **clone attach 
function**. This function accepts
- * two parameters, `function(clone, scope) { ... }`, where the `clone` is a 
fresh compiled copy of your transcluded
- * content and the `scope` is the newly created transclusion scope, to which 
the clone is bound.
- *
- * <div class="alert alert-info">
- * **Best Practice**: Always provide a `cloneFn` (clone attach function) when 
you call a translude function
- * since you then get a fresh clone of the original DOM and also have access 
to the new transclusion scope.
- * </div>
- *
- * It is normal practice to attach your transcluded content (`clone`) to the 
DOM inside your **clone
- * attach function**:
- *
- * ```js
- * var transcludedContent, transclusionScope;
- *
- * $transclude(function(clone, scope) {
- *   element.append(clone);
- *   transcludedContent = clone;
- *   transclusionScope = scope;
- * });
- * ```
- *
- * Later, if you want to remove the transcluded content from your DOM then you 
should also destroy the
- * associated transclusion scope:
- *
- * ```js
- * transcludedContent.remove();
- * transclusionScope.$destroy();
- * ```
- *
- * <div class="alert alert-info">
- * **Best Practice**: if you intend to add and remove transcluded content 
manually in your directive
- * (by calling the transclude function to get the DOM and and calling 
`element.remove()` to remove it),
- * then you are also responsible for calling `$destroy` on the transclusion 
scope.
- * </div>
- *
- * The built-in DOM manipulation directives, such as address@hidden ngIf}, 
address@hidden ngSwitch} and address@hidden ngRepeat}
- * automatically destroy their transluded clones as necessary so you do not 
need to worry about this if
- * you are simply using address@hidden ngTransclude} to inject the 
transclusion into your directive.
- *
- *
- * #### Transclusion Scopes
- *
- * When you call a transclude function it returns a DOM fragment that is 
pre-bound to a **transclusion
- * scope**. This scope is special, in that it is a child of the directive's 
scope (and so gets destroyed
- * when the directive's scope gets destroyed) but it inherits the properties 
of the scope from which it
- * was taken.
- *
- * For example consider a directive that uses transclusion and isolated scope. 
The DOM hierarchy might look
- * like this:
- *
- * ```html
- * <div ng-app>
- *   <div isolate>
- *     <div transclusion>
- *     </div>
- *   </div>
- * </div>
- * ```
- *
- * The `$parent` scope hierarchy will look like this:
- *
- * ```
- * - $rootScope
- *   - isolate
- *     - transclusion
- * ```
- *
- * but the scopes will inherit prototypically from different scopes to their 
`$parent`.
- *
- * ```
- * - $rootScope
- *   - transclusion
- * - isolate
- * ```
- *
- *
- * ### Attributes
- *
- * The address@hidden ng.$compile.directive.Attributes Attributes} object - 
passed as a parameter in the
- * `link()` or `compile()` functions. It has a variety of uses.
- *
- * accessing *Normalized attribute names:*
- * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', 
`data-ng-bind`, or 'x-ng-bind'.
- * the attributes object allows for normalized access to
- *   the attributes.
- *
- * * *Directive inter-communication:* All directives share the same instance 
of the attributes
- *   object which allows the directives to use the attributes object as inter 
directive
- *   communication.
- *
- * * *Supports interpolation:* Interpolation attributes are assigned to the 
attribute object
- *   allowing other directives to read the interpolated value.
- *
- * * *Observing interpolated attributes:* Use `$observe` to observe the value 
changes of attributes
- *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very 
efficient but it's also
- *   the only way to easily get the actual value because during the linking 
phase the interpolation
- *   hasn't been evaluated yet and so the value is at this time set to 
`undefined`.
- *
- * ```js
- * function linkingFn(scope, elm, attrs, ctrl) {
- *   // get the attribute value
- *   console.log(attrs.ngModel);
- *
- *   // change the attribute
- *   attrs.$set('ngModel', 'new value');
- *
- *   // observe changes to interpolated attribute
- *   attrs.$observe('ngModel', function(value) {
- *     console.log('ngModel has changed value to ' + value);
- *   });
- * }
- * ```
- *
- * ## Example
- *
- * <div class="alert alert-warning">
- * **Note**: Typically directives are registered with `module.directive`. The 
example below is
- * to illustrate how `$compile` works.
- * </div>
- *
- <example module="compileExample">
-   <file name="index.html">
-    <script>
-      angular.module('compileExample', [], function($compileProvider) {
-        // configure new 'compile' directive by passing a directive
-        // factory function. The factory function injects the '$compile'
-        $compileProvider.directive('compile', function($compile) {
-          // directive factory creates a link function
-          return function(scope, element, attrs) {
-            scope.$watch(
-              function(scope) {
-                 // watch the 'compile' expression for changes
-                return scope.$eval(attrs.compile);
-              },
-              function(value) {
-                // when the 'compile' expression changes
-                // assign it into the current DOM
-                element.html(value);
-
-                // compile the new DOM and link it to the current
-                // scope.
-                // NOTE: we only compile .childNodes so that
-                // we don't get into infinite loop compiling ourselves
-                $compile(element.contents())(scope);
-              }
-            );
-          };
-        });
-      })
-      .controller('GreeterController', ['$scope', function($scope) {
-        $scope.name = 'Angular';
-        $scope.html = 'Hello {{name}}';
-      }]);
-    </script>
-    <div ng-controller="GreeterController">
-      <input ng-model="name"> <br>
-      <textarea ng-model="html"></textarea> <br>

-       expect(output.getText()).toBe('Hello Angular');
-       textarea.clear();

- * **Note:** Passing a `transclude` function to the $compile function is 
deprecated, as it
- *   e.g. will not use the right outer scope. Please pass the transclude

- * </div>
- *
- * @param {number} maxPriority only apply directives lower than given priority 
(Only effects the

is used to bind template
- * (a DOM element/tree) to a scope. Where:
- *
- *  * `scope` - A address@hidden ng.$rootScope.Scope Scope} to bind to.
- *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function 
will clone the
- *  `template` and call the `cloneAttachFn` function allowing the caller to 
attach the
- *  cloned elements to the DOM document at the appropriate place. The 
`cloneAttachFn` is
- *  called as: <br> `cloneAttachFn(clonedElement, scope)` where:
- *
- *      * `clonedElement` - is a clone of the original `element` passed into 
the compiler.
- *      * `scope` - is the current scope with which the linking function is 
working with.
- *
- *  * `options` - An optional object hash with linking options. If `options` 
is provided, then the following
- *  keys may be used to control linking behavior:
- *
- *      * `parentBoundTranscludeFn` - the transclude function made available to
- *        directives; if given, it will be passed through to the link 
functions of
- *        directives found in `element` during compilation.
- *      * `transcludeControllers` - an object hash with keys that map 
controller names
- *        to controller instances; if given, it will make the controllers
- *        available to directives.
- *      * `futureParentElement` - defines the parent to which the 
`cloneAttachFn` will add
- *        the cloned elements; only needed for transcludes that are allowed to 
contain non html
- *        elements (e.g. SVG elements). See also the directive.controller 
property.
- *
- * Calling the linking function returns the element of the template. It is 
either the original
- * element passed in, or the clone of the element if the `cloneAttachFn` is 
provided.
- *
- * After linking the view is not updated until after a call to $digest which 
typically is done by
- * Angular automatically.
- *
- * If you need access to the bound view, there are two ways to do it:
- *
- * - If you are not asking the linking function to clone the template, create 
the DOM element(s)
- *   before you send them to the compiler and keep this reference around.
- *   ```js
- *     var element = $compile('<p>{{total}}</p>')(scope);
- *   ```
- *
- * - if on the other hand, you need the element to be cloned, the view 
reference from the original
- *   example would not point to the clone, but rather to the original template 
that was cloned. In
- *   this case, you can access the clone via the cloneAttachFn:
- *   ```js
- *     var templateElement = angular.element('<p>{{total}}</p>'),
- *         scope = ....;
- *
- *     var clonedElement = $compile(templateElement)(scope, 
function(clonedElement, scope) {
- *       //attach the clone to DOM document at the right place
- *     });
- *
- *     //now we have reference to the cloned DOM via `clonedElement`
- *   ```
- *
- *
- * For information on how the compiler works, see the
- * address@hidden guide/compiler Angular HTML Compiler} section of the 
Developer Guide.

- *
- * In unit tests, if `angular-mocks.js` is loaded, this service is overridden 
by
- * address@hidden ngMock.$exceptionHandler mock $exceptionHandler} which aids 
in testing.
- *
- * ## Example:
- *
- * ```js
- *   angular.module('exceptionOverride', []).factory('$exceptionHandler', 
function() {
- *     return function(exception, cause) {
- *       exception.message += ' (caused by "' + cause + '")';

- * This example will override the normal action of `$exceptionHandler`, to 
make angular

console.
- *
- * <hr />
- * Note, that code executed in event-listeners (even those registered using 
jqLite's `on`/`bind`
- * methods) does not delegate exceptions to the address@hidden 
ng.$exceptionHandler $exceptionHandler}

-     * @description
-     * The `$http` service is a core Angular service that facilitates 
communication with the remote
-     * HTTP servers via the browser's 
[XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
-     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
-     *
-     * For unit testing applications that use `$http` service, see
-     * address@hidden ngMock.$httpBackend $httpBackend mock}.
-     *
-     * For a higher level of abstraction, please check out the address@hidden 
ngResource.$resource
-     * $resource} service.
-     *
-     * The $http API is based on the address@hidden ng.$q deferred/promise 
APIs} exposed by
-     * the $q service. While for simple usage patterns this doesn't matter 
much, for advanced usage
-     * it is important to familiarize yourself with these APIs and the 
guarantees they provide.
-     *
-     *
-     * ## General usage
-     * The `$http` service is a function which takes a single argument — a 
configuration object —
-     * that is used to generate an HTTP request and returns  a address@hidden 
ng.$q promise}
-     * with two $http specific methods: `success` and `error`.
-     *
-     * ```js
-     *   // Simple GET request example :
-     *   $http.get('/someUrl').
-     *     success(function(data, status, headers, config) {
-     *       // this callback will be called asynchronously
-     *       // when the response is available
-     *     }).
-     *     error(function(data, status, headers, config) {
-     *       // called asynchronously if an error occurs
-     *       // or server returns response with an error status.
-     *     });
-     * ```
-     *
-     * ```js
-     *   // Simple POST request example (passing data) :
-     *   $http.post('/someUrl', {msg:'hello word!'}).
-     *     success(function(data, status, headers, config) {
-     *       // this callback will be called asynchronously
-     *       // when the response is available
-     *     }).
-     *     error(function(data, status, headers, config) {
-     *       // called asynchronously if an error occurs
-     *       // or server returns response with an error status.
-     *     });
-     * ```
-     *
-     *
-     * Since the returned value of calling the $http function is a `promise`, 
you can also use
-     * the `then` method to register callbacks, and these callbacks will 
receive a single argument –
-     * an object representing the response. See the API signature and type 
info below for more
-     * details.
-     *
-     * A response status code between 200 and 299 is considered a success 
status and
-     * will result in the success callback being called. Note that if the 
response is a redirect,
-     * XMLHttpRequest will transparently follow it, meaning that the error 
callback will not be
-     * called for such responses.
-     *
-     * ## Writing Unit Tests that use $http
-     * When unit testing (using address@hidden ngMock ngMock}), it is 
necessary to call
-     * address@hidden ngMock.$httpBackend#flush $httpBackend.flush()} to flush 
each pending
-     * request using trained responses.
-     *
-     * ```
-     * $httpBackend.expectGET(...);
-     * $http.get(...);
-     * $httpBackend.flush();
-     * ```
-     *
-     * ## Shortcut methods
-     *
-     * Shortcut methods are also available. All shortcut methods require 
passing in the URL, and
-     * request data must be passed in for POST/PUT requests.
-     *
-     * ```js
-     *   $http.get('/someUrl').success(successCallback);
-     *   $http.post('/someUrl', data).success(successCallback);
-     * ```
-     *
-     * Complete list of shortcut methods:
-     *
-     * - address@hidden ng.$http#get $http.get}
-     * - address@hidden ng.$http#head $http.head}
-     * - address@hidden ng.$http#post $http.post}
-     * - address@hidden ng.$http#put $http.put}
-     * - address@hidden ng.$http#delete $http.delete}
-     * - address@hidden ng.$http#jsonp $http.jsonp}
-     * - address@hidden ng.$http#patch $http.patch}
-     *
-     *
-     * ## Setting HTTP Headers
-     *
-     * The $http service will automatically add certain HTTP headers to all 
requests. These defaults
-     * can be fully configured by accessing the 
`$httpProvider.defaults.headers` configuration
-     * object, which currently contains this default configuration:
-     *
-     * - `$httpProvider.defaults.headers.common` (headers that are common for 
all requests):
-     *   - `Accept: application/json, text/plain, * / *`
-     * - `$httpProvider.defaults.headers.post`: (header defaults for POST 
requests)
-     *   - `Content-Type: application/json`
-     * - `$httpProvider.defaults.headers.put` (header defaults for PUT 
requests)
-     *   - `Content-Type: application/json`
-     *
-     * To add or overwrite these defaults, simply add or remove a property 
from these configuration
-     * objects. To add headers for an HTTP method other than POST or PUT, 
simply add a new object
-     * with the lowercased HTTP method name as the key, e.g.
-     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }.
-     *
-     * The defaults can also be set at runtime via the `$http.defaults` object 
in the same
-     * fashion. For example:
-     *
-     * ```
-     * module.run(function($http) {
-     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'
-     * });
-     * ```
-     *
-     * In addition, you can supply a `headers` property in the config object 
passed when
-     * calling `$http(config)`, which overrides the defaults without changing 
them globally.
-     *
-     * To explicitly remove a header automatically added via 
$httpProvider.defaults.headers on a per request basis,
-     * Use the `headers` property, setting the desired header to `undefined`. 
For example:
-     *
-     * ```js
-     * var req = {
-     *  method: 'POST',
-     *  url: 'http://example.com',
-     *  headers: {
-     *    'Content-Type': undefined
-     *  },
-     *  data: { test: 'test' },
-     * }
-     *
-     * $http(req).success(function(){...}).error(function(){...});
-     * ```
-     *
-     * ## Transforming Requests and Responses
-     *
-     * Both requests and responses can be transformed using transformation 
functions: `transformRequest`
-     * and `transformResponse`. These properties can be a single function that 
returns
-     * the transformed value (`{function(data, headersGetter)`) or an array of 
such transformation functions,
-     * which allows you to `push` or `unshift` a new transformation function 
into the transformation chain.
-     *
-     * ### Default Transformations
-     *
-     * The `$httpProvider` provider and `$http` service expose 
`defaults.transformRequest` and
-     * `defaults.transformResponse` properties. If a request does not provide 
its own transformations
-     * then these will be applied.
-     *
-     * You can augment or replace the default transformations by modifying 
these properties by adding to or
-     * replacing the array.
-     *
-     * Angular provides the following default transformations:
-     *
-     * Request transformations (`$httpProvider.defaults.transformRequest` and 
`$http.defaults.transformRequest`):
-     *
-     * - If the `data` property of the request configuration object contains 
an object, serialize it
-     *   into JSON format.
-     *
-     * Response transformations (`$httpProvider.defaults.transformResponse` 
and `$http.defaults.transformResponse`):
-     *
-     *  - If XSRF prefix is detected, strip it (see Security Considerations 
section below).
-     *  - If JSON response is detected, deserialize it using a JSON parser.
-     *
-     *
-     * ### Overriding the Default Transformations Per Request
-     *
-     * If you wish override the request/response transformations only for a 
single request then provide
-     * `transformRequest` and/or `transformResponse` properties on the 
configuration object passed
-     * into `$http`.
-     *
-     * Note that if you provide these properties on the config object the 
default transformations will be
-     * overwritten. If you wish to augment the default transformations then 
you must include them in your
-     * local transformation array.
-     *
-     * The following code demonstrates adding a new response transformation to 
be run after the default response
-     * transformations have been run.
-     *
-     * ```js
-     * function appendTransform(defaults, transform) {
-     *
-     *   // We can't guarantee that the default transformation is an array
-     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
-     *
-     *   // Append the new transformation to the defaults
-     *   return defaults.concat(transform);
-     * }
-     *
-     * $http({
-     *   url: '...',
-     *   method: 'GET',
-     *   transformResponse: appendTransform($http.defaults.transformResponse, 
function(value) {
-     *     return doTransform(value);
-     *   })
-     * });
-     * ```
-     *
-     *
-     * ## Caching
-     *
-     * To enable caching, set the request configuration `cache` property to 
`true` (to use default
-     * cache) or to a custom cache object (built with address@hidden 
ng.$cacheFactory `$cacheFactory`}).
-     * When the cache is enabled, `$http` stores the response from the server 
in the specified
-     * cache. The next time the same request is made, the response is served 
from the cache without
-     * sending a request to the server.
-     *
-     * Note that even if the response is served from cache, delivery of the 
data is asynchronous in
-     * the same way that real requests are.
-     *
-     * If there are multiple GET requests for the same URL that should be 
cached using the same
-     * cache, but the cache is not populated yet, only one request to the 
server will be made and
-     * the remaining requests will be fulfilled using the response from the 
first request.
-     *
-     * You can change the default cache to a new object (built with
-     * address@hidden ng.$cacheFactory `$cacheFactory`}) by updating the
-     * address@hidden ng.$http#defaults `$http.defaults.cache`} property. All 
requests who set
-     * their `cache` property to `true` will now use this cache object.
-     *
-     * If you set the default cache to `false` then only requests that specify 
their own custom
-     * cache object will be cached.
-     *
-     * ## Interceptors
-     *
-     * Before you start creating interceptors, be sure to understand the
-     * address@hidden ng.$q $q and deferred/promise APIs}.
-     *
-     * For purposes of global error handling, authentication, or any kind of 
synchronous or
-     * asynchronous pre-processing of request or postprocessing of responses, 
it is desirable to be
-     * able to intercept requests before they are handed to the server and
-     * responses before they are handed over to the application code that
-     * initiated these requests. The interceptors leverage the address@hidden 
ng.$q
-     * promise APIs} to fulfill this need for both synchronous and 
asynchronous pre-processing.
-     *
-     * The interceptors are service factories that are registered with the 
`$httpProvider` by
-     * adding them to the `$httpProvider.interceptors` array. The factory is 
called and
-     * injected with dependencies (if specified) and returns the interceptor.
-     *
-     * There are two kinds of interceptors (and two kinds of rejection 
interceptors):
-     *
-     *   * `request`: interceptors get called with a http `config` object. The 
function is free to
-     *     modify the `config` object or create a new one. The function needs 
to return the `config`
-     *     object directly, or a promise containing the `config` or a new 
`config` object.
-     *   * `requestError`: interceptor gets called when a previous interceptor 
threw an error or
-     *     resolved with a rejection.
-     *   * `response`: interceptors get called with http `response` object. 
The function is free to
-     *     modify the `response` object or create a new one. The function 
needs to return the `response`
-     *     object directly, or as a promise containing the `response` or a new 
`response` object.
-     *   * `responseError`: interceptor gets called when a previous 
interceptor threw an error or
-     *     resolved with a rejection.
-     *
-     *
-     * ```js
-     *   // register the interceptor as a service
-     *   $provide.factory('myHttpInterceptor', function($q, dependency1, 
dependency2) {
-     *     return {
-     *       // optional method
-     *       'request': function(config) {
-     *         // do something on success
-     *         return config;
-     *       },
-     *
-     *       // optional method
-     *      'requestError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       },
-     *
-     *
-     *
-     *       // optional method
-     *       'response': function(response) {
-     *         // do something on success
-     *         return response;
-     *       },
-     *
-     *       // optional method
-     *      'responseError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       }
-     *     };
-     *   });
-     *
-     *   $httpProvider.interceptors.push('myHttpInterceptor');
-     *
-     *
-     *   // alternatively, register the interceptor via an anonymous factory
-     *   $httpProvider.interceptors.push(function($q, dependency1, 
dependency2) {
-     *     return {
-     *      'request': function(config) {
-     *          // same as above
-     *       },
-     *
-     *       'response': function(response) {
-     *          // same as above
-     *       }
-     *     };
-     *   });
-     * ```
-     *
-     * ## Security Considerations
-     *
-     * When designing web applications, consider security threats from:
-     *
-     * - [JSON 
vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
-     *
-     * Both server and the client must cooperate in order to eliminate these 
threats. Angular comes
-     * pre-configured with strategies that address these issues, but for this 
to work backend server
-     * cooperation is required.
-     *
-     * ### JSON Vulnerability Protection
-     *
-     * A [JSON 
vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * allows third party website to turn your JSON resource URL into
-     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some 
conditions. To
-     * counter this your server can prefix all JSON requests with following 
string `")]}',\n"`.
-     * Angular will automatically strip the prefix before processing it as 
JSON.
-     *
-     * For example if your server needs to return:
-     * ```js
-     * ['one','two']
-     * ```
-     *
-     * which is vulnerable to attack, your server can return:
-     * ```js
-     * )]}',
-     * ['one','two']
-     * ```
-     *
-     * Angular will strip the prefix, before processing the JSON.
-     *
-     *
-     * ### Cross Site Request Forgery (XSRF) Protection
-     *
-     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a 
technique by which
-     * an unauthorized site can gain your user's private data. Angular 
provides a mechanism
-     * to counter XSRF. When performing XHR requests, the $http service reads 
a token from a cookie
-     * (by default, `XSRF-TOKEN`) and sets it as an HTTP header 
(`X-XSRF-TOKEN`). Since only
-     * JavaScript that runs on your domain could read the cookie, your server 
can be assured that
-     * the XHR came from JavaScript running on your domain. The header will 
not be set for
-     * cross-domain requests.
-     *
-     * To take advantage of this, your server needs to set a token in a 
JavaScript readable session
-     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent 
XHR requests the
-     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, 
and therefore be sure
-     * that only JavaScript running on your domain could have sent the 
request. The token must be
-     * unique for each user and must be verifiable by the server (to prevent 
the JavaScript from
-     * making up its own tokens). We recommend that the token is a digest of 
your site's
-     * authentication cookie with a 
[salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
-     * for added security.
-     *
-     * The name of the headers can be specified using the xsrfHeaderName and 
xsrfCookieName
-     * properties of either $httpProvider.defaults at config-time, 
$http.defaults at run-time,
-     * or the per-request config object.
-     *
-     *
-     * @param {object} config Object describing the request to be made and how 
it should be
-     *    processed. The object has following properties:
-     *
-     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
-     *    - **url** – `{string}` – Absolute or relative URL of the resource 
that is being requested.
-     *    - **params** – `{Object.<string|Object>}` – Map of strings or 
objects which will be turned
-     *      to `?key1=value1&key2=value2` after the url. If the value is not a 
string, it will be
-     *      JSONified.
-     *    - **data** – `{string|Object}` – Data to be sent as the request 
message data.
-     *    - **headers** – `{Object}` – Map of strings or functions which 
return strings representing
-     *      HTTP headers to send to the server. If the return value of a 
function is null, the
-     *      header will not be sent.
-     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate 
with the XSRF token.
-     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the 
XSRF token.
-     *    - **transformRequest** –
-     *      `{function(data, headersGetter)|Array.<function(data, 
headersGetter)>}` –
-     *      transform function or an array of such functions. The transform 
function takes the http
-     *      request body and headers and returns its transformed (typically 
serialized) version.
-     *      See address@hidden 
#overriding-the-default-transformations-per-request Overriding the Default 
Transformations}
-     *    - **transformResponse** –
-     *      `{function(data, headersGetter)|Array.<function(data, 
headersGetter)>}` –
-     *      transform function or an array of such functions. The transform 
function takes the http
-     *      response body and headers and returns its transformed (typically 
deserialized) version.
-     *      See address@hidden 
#overriding-the-default-transformations-per-request Overriding the Default 
Transformations}
-     *    - **cache** – `{boolean|Cache}` – If true, a default $http cache 
will be used to cache the
-     *      GET request, otherwise if a cache instance built with
-     *      address@hidden ng.$cacheFactory $cacheFactory}, this cache will be 
used for
-     *      caching.
-     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or 
address@hidden ng.$q promise}
-     *      that should abort the request when resolved.
-     *    - **withCredentials** - `{boolean}` - whether to set the 
`withCredentials` flag on the
-     *      XHR object. See [requests with 
credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
-     *      for more information.
-     *    - **responseType** - `{string}` - see
-     *      
[requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
-     *
-     * @returns {HttpPromise} Returns a address@hidden ng.$q promise} object 
with the
-     *   standard `then` method and two http specific methods: `success` and 
`error`. The `then`
-     *   method takes two arguments a success and an error callback which will 
be called with a
-     *   response object. The `success` and `error` methods take a single 
argument - a function that
-     *   will be called when the request succeeds or fails respectively. The 
arguments passed into
-     *   these functions are destructured representation of the response 
object passed into the
-     *   `then` method. The response object has these properties:
-     *
-     *   - **data** – `{string|Object}` – The response body transformed with

-     *
-     * Compiles a string with markup into an interpolation function. This 
service is used by the
-     * HTML address@hidden ng.$compile $compile} service for data binding. See
-     * address@hidden ng.$interpolateProvider $interpolateProvider} for 
configuring the
-     * interpolation markup.
-     *
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var exp = $interpolate('Hello {{name | uppercase}}!');
-     *   expect(exp({name:'Angular'}).toEqual('Hello ANGULAR!');
-     * ```
-     *
-     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If 
`allOrNothing` is
-     * `true`, the interpolation function will return `undefined` unless all 
embedded expressions
-     * evaluate to a value other than `undefined`.
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var context = {greeting: 'Hello', name: undefined };
-     *
-     *   // default "forgiving" mode
-     *   var exp = $interpolate('{{greeting}} {{name}}!');
-     *   expect(exp(context)).toEqual('Hello !');
-     *
-     *   // "allOrNothing" mode
-     *   exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
-     *   expect(exp(context)).toBeUndefined();
-     *   context.name = 'Angular';
-     *   expect(exp(context)).toEqual('Hello Angular!');
-     * ```
-     *
-     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` 
use this behavior.
-     *
-     * ####Escaped Interpolation
-     * $interpolate provides a mechanism for escaping interpolation markers. 
Start and end markers
-     * can be escaped by preceding each of their characters with a REVERSE 
SOLIDUS U+005C (backslash).
-     * It will be rendered as a regular start/end marker, and will not be 
interpreted as an expression
-     * or binding.
-     *
-     * This enables web-servers to prevent script injection attacks and 
defacing attacks, to some
-     * degree, while also enabling code examples to work without relying on the
-     * address@hidden ng.directive:ngNonBindable ngNonBindable} directive.
-     *
-     * **For security purposes, it is strongly encouraged that web servers 
escape user-supplied data,
-     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; 
respectively, and replacing all
-     * interpolation start/end markers with their escaped counterparts.**
-     *
-     * Escaped interpolation markers are only replaced with the actual 
interpolation markers in rendered
-     * output when the $interpolate service processes the text. So, for HTML 
elements interpolated
-     * by address@hidden ng.$compile $compile}, or otherwise interpolated with 
the `mustHaveExpression` parameter
-     * set to `true`, the interpolated text must contain an unescaped 
interpolation expression. As such,
-     * this is typically useful only when user-data is used in rendering a 
template from the server, or
-     * when otherwise untrusted data is used by a directive.
-     *
-     * <example>
-     *  <file name="index.html">
-     *    <div ng-init="username='A user'">
-     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username 
= "defaced value"; \}\}
-     *        </p>
-     *      <p><strong>{{username}}</strong> attempts to inject code which 
will deface the
-     *        application, but fails to accomplish their task, because the 
server has correctly
-     *        escaped the interpolation start/end markers with REVERSE SOLIDUS 
U+005C (backslash)
-     *        characters.</p>
-     *      <p>Instead, the result of the attempted script injection is 
visible, and can be removed
-     *        from the database by an administrator.</p>

- * @description
- * Simple service for logging. Default implementation safely writes the message
- * into the browser's console (if present).
- *
- * The main purpose of this service is to simplify debugging and 
troubleshooting.
- *
- * The default is to log `debug` messages. You can use
- * address@hidden ng.$logProvider ng.$logProvider#debugEnabled} to change this.
- *
- * @example
-   <example module="logExample">
-     <file name="script.js">
-       angular.module('logExample', [])
-         .controller('LogController', ['$scope', '$log', function($scope,

-// Sandboxing Angular Expressions
-// ------------------------------
-// Angular expressions are generally considered safe because these expressions 
only have direct
-// access to `$scope` and locals. However, one can obtain the ability to 
execute arbitrary JS code by
-// obtaining a reference to native JS functions such as the Function 
constructor.
-//
-// As an example, consider the following Angular expression:
-//
-//   {}.toString.constructor('alert("evil JS code")')
-//
-// This sandboxing technique is not perfect and doesn't aim to be. The goal is 
to prevent exploits
-// against the expression language, but not to prevent exploits that were 
enabled by exposing
-// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a 
Scope is never a good
-// practice and therefore we are not even trying to protect against 
interaction with an object
-// explicitly exposed in this way.
-//
-// In general, it is not possible to access a Window object from an angular 
expression unless a
-// window or some DOM object that has a reference to window is published onto 
a Scope.
-// Similarly we prevent invocations of function known to be dangerous, as well 
as assignments to
-// native objects.
-//
-// See https://docs.angularjs.org/guide/security

-/**
- * @ngdoc service
- * @name $q
- * @requires $rootScope
- *
- * @description
- * A service that helps you run functions asynchronously, and use their return 
values (or exceptions)
- * when they are done processing.
- *
- * This is an implementation of promises/deferred objects inspired by
- * [Kris Kowal's Q](https://github.com/kriskowal/q).
- *
- * $q can be used in two fashions --- one which is more similar to Kris 
Kowal's Q or jQuery's Deferred
- * implementations, and the other which resembles ES6 promises to some degree.
- *
- * # $q constructor
- *
- * The streamlined ES6 style promise is essentially just using $q as a 
constructor which takes a `resolver`
- * function as the first argument. This is similar to the native Promise 
implementation from ES6 Harmony,
- * see 
[MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
- *
- * While the constructor-style use is supported, not all of the supporting 
methods from ES6 Harmony promises are
- * available yet.
- *
- * It can be used like so:
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q` and 
`okToGreet`
- *   // are available in the current lexical scope (they could have been 
injected or passed in).
- *
- *   function asyncGreet(name) {
- *     // perform some asynchronous operation, resolve or reject the promise 
when appropriate.
- *     return $q(function(resolve, reject) {
- *       setTimeout(function() {
- *         if (okToGreet(name)) {
- *           resolve('Hello, ' + name + '!');
- *         } else {
- *           reject('Greeting ' + name + ' is not allowed.');
- *         }
- *       }, 1000);
- *     });
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   });
- * ```
- *
- * Note: progress/notify callbacks are not currently supported via the 
ES6-style interface.
- *
- * However, the more traditional CommonJS-style usage is still available, and 
documented below.
- *
- * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) 
describes a promise as an
- * interface for interacting with an object that represents the result of an 
action that is
- * performed asynchronously, and may or may not be finished at any given point 
in time.
- *
- * From the perspective of dealing with error handling, deferred and promise 
APIs are to
- * asynchronous programming what `try`, `catch` and `throw` keywords are to 
synchronous programming.
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q` and 
`okToGreet`
- *   // are available in the current lexical scope (they could have been 
injected or passed in).
- *
- *   function asyncGreet(name) {
- *     var deferred = $q.defer();
- *
- *     setTimeout(function() {
- *       deferred.notify('About to greet ' + name + '.');
- *
- *       if (okToGreet(name)) {
- *         deferred.resolve('Hello, ' + name + '!');
- *       } else {
- *         deferred.reject('Greeting ' + name + ' is not allowed.');
- *       }
- *     }, 1000);
- *
- *     return deferred.promise;
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   }, function(update) {
- *     alert('Got notification: ' + update);
- *   });
- * ```
- *
- * At first it might not be obvious why this extra complexity is worth the 
trouble. The payoff
- * comes in the way of guarantees that promise and deferred APIs make, see
- * 
https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
- *
- * Additionally the promise api allows for composition that is very hard to do 
with the
- * traditional callback 
([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
- * For more on this please see the [Q 
documentation](https://github.com/kriskowal/q) especially the
- * section on serial or parallel joining of promises.
- *
- * # The Deferred API
- *
- * A new instance of deferred is constructed by calling `$q.defer()`.
- *
- * The purpose of the deferred object is to expose the associated Promise 
instance as well as APIs
- * that can be used for signaling the successful or unsuccessful completion, 
as well as the status
- * of the task.
- *
- * **Methods**
- *
- * - `resolve(value)` – resolves the derived promise with the `value`. If the 
value is a rejection
- *   constructed via `$q.reject`, the promise will be rejected instead.
- * - `reject(reason)` – rejects the derived promise with the `reason`. This is 
equivalent to
- *   resolving it with a rejection constructed via `$q.reject`.
- * - `notify(value)` - provides updates on the status of the promise's 
execution. This may be called
- *   multiple times before the promise is either resolved or rejected.
- *
- * **Properties**
- *
- * - promise – `{Promise}` – promise object associated with this deferred.
- *
- *
- * # The Promise API
- *
- * A new promise instance is created when a deferred instance is created and 
can be retrieved by
- * calling `deferred.promise`.
- *
- * The purpose of the promise object is to allow for interested parties to get 
access to the result
- * of the deferred task when it completes.
- *
- * **Methods**
- *
- * - `then(successCallback, errorCallback, notifyCallback)` – regardless of 
when the promise was or
- *   will be resolved or rejected, `then` calls one of the success or error 
callbacks asynchronously
- *   as soon as the result is available. The callbacks are called with a 
single argument: the result
- *   or rejection reason. Additionally, the notify callback may be called zero 
or more times to
- *   provide a progress indication, before the promise is resolved or rejected.
- *
- *   This method *returns a new promise* which is resolved or rejected via the 
return value of the
- *   `successCallback`, `errorCallback`. It also notifies via the return value 
of the
- *   `notifyCallback` method. The promise cannot be resolved or rejected from 
the notifyCallback
- *   method.
- *
- * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
- *
- * - `finally(callback, notifyCallback)` – allows you to observe either the 
fulfillment or rejection of a promise,
- *   but to do so without modifying the final value. This is useful to release 
resources or do some
- *   clean-up that needs to be done whether the promise was rejected or 
resolved. See the [full
- *   
specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback)
 for
- *   more information.
- *
- * # Chaining promises
- *
- * Because calling the `then` method of a promise returns a new derived 
promise, it is easily
- * possible to create a chain of promises:
- *
- * ```js
- *   promiseB = promiseA.then(function(result) {
- *     return result + 1;
- *   });
- *
- *   // promiseB will be resolved immediately after promiseA is resolved and 
its value
- *   // will be the result of promiseA incremented by 1
- * ```
- *
- * It is possible to create chains of any length and since a promise can be 
resolved with another
- * promise (which will defer its resolution further), it is possible to 
pause/defer resolution of
- * the promises at any point in the chain. This makes it possible to implement 
powerful APIs like
- * $http's response interceptors.
- *
- *
- * # Differences between Kris Kowal's Q and $q
- *
- *  There are two main differences:
- *
- * - $q is integrated with the address@hidden ng.$rootScope.Scope} Scope model 
observation
- *   mechanism in angular, which means faster propagation of resolution or 
rejection into your
- *   models and avoiding unnecessary browser repaints, which would result in 
flickering UI.
- * - Q has many more features than $q, but that comes at a cost of bytes. $q 
is tiny, but contains
- *   all the important functionality needed for common async tasks.
- *
- *  # Testing
- *
- *  ```js
- *    it('should simulate promise', inject(function($q, $rootScope) {
- *      var deferred = $q.defer();
- *      var promise = deferred.promise;
- *      var resolvedValue;
- *
- *      promise.then(function(value) { resolvedValue = value; });
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Simulate resolving of promise
- *      deferred.resolve(123);
- *      // Note that the 'then' function does not get called synchronously.
- *      // This is because we want the promise API to always be async, whether 
or not
- *      // it got called synchronously or asynchronously.
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Propagate promise resolution to 'then' functions using $apply().
- *      $rootScope.$apply();
- *      expect(resolvedValue).toEqual(123);
- *    }));
- *  ```
- *
- * @param {function(function, function)} resolver Function which is 
responsible for resolving or
- *   rejecting the newly created promise. The first parameter is a function 
which resolves the
- *   promise, the second parameter is a function which rejects the promise.
- *
- * @returns {Promise} The newly created promise.

-   * Creates a promise that is resolved as rejected with the specified 
`reason`. This api should be
-   * used to forward rejection in a chain of promises. If you are dealing with 
the last promise in
-   * a promise chain, you don't need to worry about it.
-   *
-   * When comparing deferreds/promises to the familiar behavior of 
try/catch/throw, think of
-   * `reject` as the `throw` keyword in JavaScript. This also means that if 
you "catch" an error via
-   * a promise error callback and you want to forward the error to the promise 
derived from the
-   * current promise, you have to "rethrow" the error by returning a rejection 
constructed via
-   * `reject`.
-   *
-   * ```js
-   *   promiseB = promiseA.then(function(result) {
-   *     // success: do something and resolve promiseB
-   *     //          with the old or a new result
-   *     return result;
-   *   }, function(reason) {
-   *     // error: handle the error if possible and
-   *     //        resolve promiseB with newPromiseOrValue,
-   *     //        otherwise forward the rejection to promiseB
-   *     if (canHandle(reason)) {
-   *      // handle the error and recover
-   *      return newPromiseOrValue;
-   *     }

-/**
- * DESIGN NOTES
- *
- * The design decisions behind the scope are heavily favored for speed and 
memory consumption.
- *
- * The typical use of scope is to watch the expressions, which most of the 
time return the same
- * value as last time so we optimize the operation.
- *
- * Closures construction is expensive in terms of speed as well as memory:
- *   - No closures, instead use prototypical inheritance for API
- *   - Internal state needs to be stored on scope directly, which means that 
private state is
- *     exposed as $$____ properties
- *
- * Loop operations are optimized by using while(count--) { ... }
- *   - this means that in order to keep the same order of execution as 
addition we have to add
- *     items to the array at the beginning (unshift) instead of at the end 
(push)
- *
- * Child scopes are created and removed often
- *   - Using an array would be slow since inserts in middle are expensive so 
we use linked list
- *
- * There are few watches then a lot of observers. This is why you don't want 
the observer to be
- * implemented in the same way as watch. Watch requires return of 
initialization function which
- * are expensive to construct.

-       * - When `objectEquality == true`, inequality of the `watchExpression` 
is determined
-       *   according to the address@hidden angular.equals} function. To save 
the value of the object for
-       *   later comparison, the address@hidden angular.copy} function is 
used. This therefore means that
-       *   watching complex objects will have adverse memory and performance 
implications.
-       * - The watch `listener` may change the model, which may trigger other 
`listener`s to fire.
-       *   This is achieved by rerunning the watchers until no changes are 
detected. The rerun
-       *   iteration limit is 10 to prevent an infinite loop deadlock.
-       *
-       *
-       * If you want to be notified whenever address@hidden 
ng.$rootScope.Scope#$digest $digest} is called,
-       * you can register a `watchExpression` function with no `listener`. 
(Since `watchExpression`
-       * can execute multiple times per address@hidden 
ng.$rootScope.Scope#$digest $digest} cycle when a
-       * change is detected, be prepared for multiple calls to your listener.)
-       *
-       * After a watcher is registered with the scope, the `listener` fn is 
called asynchronously
-       * (via address@hidden ng.$rootScope.Scope#$evalAsync $evalAsync}) to 
initialize the
-       * watcher. In rare cases, this is undesirable because the listener is 
called when the result
-       * of `watchExpression` didn't change. To detect this scenario within 
the `listener` fn, you
-       * can compare the `newVal` and `oldVal`. If these two values are 
identical (`===`) then the
-       * listener was called due to initialization.
-       *
-       *
-       *

- *
- * `$sceDelegate` is a service that is used by the `$sce` service to provide

- *
- * Typically, you would configure or override the address@hidden 
ng.$sceDelegate $sceDelegate} instead of
- * the `$sce` service to customize the way Strict Contextual Escaping works in 
AngularJS.  This is
- * because, while the `$sce` provides numerous shorthand methods, etc., you 
really only need to
- * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to 
replace the way things
- * work because `$sce` delegates to `$sceDelegate` for these operations.
- *
- * Refer address@hidden ng.$sceDelegateProvider $sceDelegateProvider} to 
configure this service.
- *
- * The default instance of `$sceDelegate` should work out of the box with 
little pain.  While you
- * can override it completely to change the behavior of `$sce`, the common 
case would
- * involve configuring the address@hidden ng.$sceDelegateProvider 
$sceDelegateProvider} instead by setting
- * your own whitelists and blacklists for trusting URLs used for loading 
AngularJS resources such as
- * templates.  Refer address@hidden

- * @ngdoc service
- * @name $sce
- * @kind function
- *
- * @description
- *
- * `$sce` is a service that provides Strict Contextual Escaping services to 
AngularJS.
- *
- * # Strict Contextual Escaping
- *
- * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires 
bindings in certain
- * contexts to result in a value that is marked as safe to use for that 
context.  One example of
- * such a context is binding arbitrary html controlled by the user via 
`ng-bind-html`.  We refer
- * to these contexts as privileged or SCE contexts.
- *
- * As of version 1.2, Angular ships with SCE enabled by default.
- *
- * Note:  When enabled (the default), IE<11 in quirks mode is not supported.  
In this mode, IE<11 allow
- * one to execute arbitrary javascript by the use of the expression() syntax.  
Refer
- * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to 
learn more about them.
- * You can ensure your document is in standards mode and not quirks mode by 
adding `<!doctype html>`
- * to the top of your HTML document.
- *
- * SCE assists in writing code in way that (a) is secure by default and (b) 
makes auditing for
- * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
- *
- * Here's an example of a binding in a privileged context:
- *
- * ```
- * <input ng-model="userHtml">
- * <div ng-bind-html="userHtml"></div>
- * ```
- *
- * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  
With SCE
- * disabled, this application allows the user to render arbitrary HTML into 
the DIV.
- * In a more realistic example, one may be rendering user comments, blog 
articles, etc. via
- * bindings.  (HTML is just one example of a context where rendering user 
controlled input creates
- * security vulnerabilities.)
- *
- * For the case of HTML, you might use a library, either on the client side, 
or on the server side,
- * to sanitize unsafe HTML before binding to the value and rendering it in the 
document.
- *
- * How would you ensure that every place that used these types of bindings was 
bound to a value that
- * was sanitized by your library (or returned as safe for rendering by your 
server?)  How can you
- * ensure that you didn't accidentally delete the line that sanitized the 
value, or renamed some
- * properties/fields and forgot to update the binding to the sanitized value?
- *
- * To be secure by default, you want to ensure that any such bindings are 
disallowed unless you can
- * determine that something explicitly says it's safe to use a value for 
binding in that
- * context.  You can then audit your code (a simple grep would do) to ensure 
that this is only done
- * for those values that you can easily tell are safe - because they were 
received from your server,
- * sanitized by your library, etc.  You can organize your codebase to help 
with this - perhaps
- * allowing only the files in a specific directory to do this.  Ensuring that 
the internal API
- * exposed by that code doesn't markup arbitrary values as safe then becomes a 
more manageable task.
- *
- * In the case of AngularJS' SCE service, one uses address@hidden 
ng.$sce#trustAs $sce.trustAs}
- * (and shorthand methods such as address@hidden ng.$sce#trustAsHtml 
$sce.trustAsHtml}, etc.) to
- * obtain values that will be accepted by SCE / privileged contexts.
- *
- *
- * ## How does it work?
- *
- * In privileged contexts, directives and code will bind to the result of 
address@hidden ng.$sce#getTrusted
- * $sce.getTrusted(context, value)} rather than to the value directly.  
Directives use address@hidden
- * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute 
bindings, which performs the
- * address@hidden ng.$sce#getTrusted $sce.getTrusted} behind the scenes on 
non-constant literals.
- *
- * As an example, address@hidden ng.directive:ngBindHtml ngBindHtml} uses 
address@hidden
- * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the 
actual code (slightly
- * simplified):
- *
- * ```
- * var ngBindHtmlDirective = ['$sce', function($sce) {
- *   return function(scope, element, attr) {
- *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
- *       element.html(value || '');
- *     });
- *   };
- * }];
- * ```
- *
- * ## Impact on loading templates
- *
- * This applies both to the address@hidden ng.directive:ngInclude 
`ng-include`} directive as well as
- * `templateUrl`'s specified by address@hidden guide/directive directives}.
- *
- * By default, Angular only loads templates from the same domain and protocol 
as the application
- * document.  This is done by calling address@hidden 
ng.$sce#getTrustedResourceUrl
- * $sce.getTrustedResourceUrl} on the template URL.  To load templates from 
other domains and/or
- * protocols, you may either either address@hidden 
ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
- * them} or address@hidden ng.$sce#trustAsResourceUrl wrap it} into a trusted 
value.
- *
- * *Please note*:
- * The browser's
- * [Same Origin 
Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy apply in addition to this and may further restrict whether the 
template is successfully
- * loaded.  This means that without the right CORS policy, loading templates 
from a different domain
- * won't work on all browsers.  Also, loading templates from `file://` URL 
does not work on some
- * browsers.
- *
- * ## This feels like too much overhead
- *
- * It's important to remember that SCE only applies to interpolation 
expressions.
- *
- * If your expressions are constant literals, they're automatically trusted 
and you don't need to
- * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) 
(e.g.
- * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
- *
- * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs 
and do not pass them
- * through address@hidden ng.$sce#getTrusted $sce.getTrusted}.  SCE doesn't 
play a role here.
- *
- * The included address@hidden ng.$sceDelegate $sceDelegate} comes with sane 
defaults to allow you to load
- * templates in `ng-include` from your application's domain without having to 
even know about SCE.
- * It blocks loading templates from other domains or loading templates over 
http from an https
- * served document.  You can change these by setting your own custom 
address@hidden
- * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and address@hidden
- * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such 
URLs.
- *
- * This significantly reduces the overhead.  It is far easier to pay the small 
overhead and have an
- * application that's secure and can be audited to verify that with much more 
ease than bolting
- * security onto an application later.
- *
- * <a name="contexts"></a>
- * ## What trusted context types are supported?
- *
- * | Context             | Notes          |
- * |---------------------|----------------|
- * | `$sce.HTML`         | For HTML that's safe to source into the 
application.  The address@hidden ng.directive:ngBindHtml ngBindHtml} directive 
uses this context for bindings. If an unsafe value is encountered and the 
address@hidden ngSanitize $sanitize} module is present this will sanitize the 
value instead of throwing an error. |
- * | `$sce.CSS`          | For CSS that's safe to source into the application. 
 Currently unused.  Feel free to use it in your own directives. |
- * | `$sce.URL`          | For URLs that are safe to follow as links.  
Currently unused (`<a href=` and `<img src=` sanitize their urls and don't 
constitute an SCE context. |
- * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, 
but whose contents are also safe to include in your application.  Examples 
include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. 
`IFRAME`, `OBJECT`, etc.)  <br><br>Note that `$sce.RESOURCE_URL` makes a 
stronger statement about the URL than `$sce.URL` does and therefore contexts 
requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that 
values trusted for `$sce.URL` are  [...]
- * | `$sce.JS`           | For JavaScript that is safe to execute in your 
application's context.  Currently unused.  Feel free to use it in your own 
directives. |
- *
- * ## Format of items in address@hidden 
ng.$sceDelegateProvider#resourceUrlWhitelist 
resourceUrlWhitelist}/address@hidden 
ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a 
name="resourceUrlPatternItem"></a>
- *
- *  Each element in these arrays must be one of the following:
- *
- *  - **'self'**
- *    - The special **string**, `'self'`, can be used to match against all 
URLs of the **same
- *      domain** as the application document using the **same protocol**.
- *  - **String** (except the special value `'self'`)
- *    - The string is matched against the full *normalized / absolute URL* of 
the resource
- *      being tested (substring matches are not good enough.)
- *    - There are exactly **two wildcard sequences** - `*` and `**`.  All 
other characters
- *      match themselves.
- *    - `*`: matches zero or more occurrences of any character other than one 
of the following 6
- *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'.  It's a useful 
wildcard for use
- *      in a whitelist.
- *    - `**`: matches zero or more occurrences of *any* character.  As such, 
it's not
- *      not appropriate to use in for a scheme, domain, etc. as it would match 
too much.  (e.g.
- *      http://**.example.com/ would match 
http://evil.com/?ignore=.example.com/ and that might
- *      not have been the intention.)  Its usage at the very end of the path 
is ok.  (e.g.
- *      http://foo.example.com/templates/**).
- *  - **RegExp** (*see caveat below*)
- *    - *Caveat*:  While regular expressions are powerful and offer great 
flexibility,  their syntax
- *      (and all the inevitable escaping) makes them *harder to maintain*.  
It's easy to
- *      accidentally introduce a bug when one updates a complex expression 
(imho, all regexes should
- *      have good test coverage.).  For instance, the use of `.` in the regex 
is correct only in a
- *      small number of cases.  A `.` character in the regex used when 
matching the scheme or a
- *      subdomain could be matched against a `:` or literal `.` that was 
likely not intended.   It
- *      is highly recommended to use the string patterns and only fall back to 
regular expressions
- *      if they as a last resort.
- *    - The regular expression must be an instance of RegExp (i.e. not a 
string.)  It is
- *      matched against the **entire** *normalized / absolute URL* of the 
resource being tested
- *      (even when the RegExp did not have the `^` and `$` codes.)  In 
addition, any flags
- *      present on the RegExp (such as multiline, global, ignoreCase) are 
ignored.
- *    - If you are generating your JavaScript from some other templating 
engine (not
- *      recommended, e.g. in issue 
[#4006](https://github.com/angular/angular.js/issues/4006)),
- *      remember to escape your regular expression (and be aware that you 
might need more than
- *      one level of escaping depending on your templating engine and the way 
you interpolated
- *      the value.)  Do make use of your platform's escaping mechanism as it 
might be good
- *      enough before coding your own.  e.g. Ruby has
- *      
[Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
- *      and Python has 
[re.escape](http://docs.python.org/library/re.html#re.escape).
- *      Javascript lacks a similar built in function for escaping.  Take a 
look at Google
- *      Closure library's [goog.string.regExpEscape(s)](
- *      
http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
- *
- * Refer address@hidden ng.$sceDelegateProvider $sceDelegateProvider} for an 
example.

- * ## Can I disable SCE completely?

application and
- * either secure it on your own or enable SCE at a later stage.  It might make 
sense to disable SCE
- * for cases where you have a lot of existing code that was written before SCE 
was introduced and
- * you're migrating them a module at a time.
- *
- * That said, here's how you can completely disable SCE:
- *
- * ```
- * angular.module('myAppWithSceDisabledmyApp', 
[]).config(function($sceProvider) {
- *   // Completely disable SCE.  For demonstration purposes only!
- *   // Do not use in new projects.
- *   $sceProvider.enabled(false);

-   * The API contract for the SCE delegate
-   * -------------------------------------
-   * The SCE delegate object must provide the following 3 methods:
-   *
-   * - trustAs(contextEnum, value)
-   *     This method is used to tell the SCE service that the provided value 
is OK to use in the
-   *     contexts specified by contextEnum.  It must return an object that 
will be accepted by
-   *     getTrusted() for a compatible contextEnum and return this value.
-   *
-   * - valueOf(value)
-   *     For values that were not produced by trustAs(), return them as is.  
For values that were
-   *     produced by trustAs(), return the corresponding input value to 
trustAs.  Basically, if
-   *     trustAs is wrapping the given values into some type, this operation 
unwraps it when given
-   *     such a value.
-   *
-   * - getTrusted(contextEnum, value)
-   *     This function should return the a value that is safe to use in the 
context specified by
-   *     contextEnum or throw and exception otherwise.
-   *
-   * NOTE: This contract deliberately does NOT state that values returned by 
trustAs() must be
-   * opaque or wrapped in some holder object.  That happens to be an 
implementation detail.  For
-   * instance, an implementation could maintain a registry of all trusted 
objects by context.  In
-   * such a case, trustAs() would return the same object that was passed in.  
getTrusted() would
-   * return the same object passed in if it was found in the registry under a 
compatible context or
-   * throw an exception otherwise.  An implementation might only wrap values 
some of the time based
-   * on some criteria.  getTrusted() might return a value and not throw an 
exception for special
-   * constants or objects even if not wrapped.  All such implementations 
fulfill this contract.
-   *
-   *
-   * A note on the inheritance model for SCE contexts
-   * ------------------------------------------------
-   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of 
URL wrapped types.  This
-   * is purely an implementation details.
-   *
-   * The contract is simply this:
-   *
-   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that 
getTrusted($sce.URL, value)
-   *     will also succeed.
-   *
-   * Inheritance happens to capture this in a natural way.  In some future, we
-   * may not use inheritance anymore.  That is OK because no code outside of
-   * sce.js and sceSpecs.js would need to be aware of this detail.

-/**
- *
- * Implementation Notes for non-IE browsers
- * ----------------------------------------
- * Assigning a URL to the href property of an anchor DOM node, even one 
attached to the DOM,
- * results both in the normalizing and parsing of the URL.  Normalizing means 
that a relative
- * URL will be resolved into an absolute URL in the context of the application 
document.
- * Parsing means that the anchor node's host, hostname, protocol, port, 
pathname and related
- * properties are all populated to reflect the normalized URL.  This approach 
has wide
- * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
- * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
- *
- * Implementation Notes for IE
- * ---------------------------
- * IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node 
similar to the other
- * browsers.  However, the parsed components will not be set if the URL 
assigned did not specify
- * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. 
will be empty.)  We
- * work around that by performing the parsing in a 2nd step by taking a 
previously normalized
- * URL (e.g. by assigning to a.href) and assigning it a.href again.  This 
correctly populates the
- * properties such as protocol, hostname, port, etc.
- *
- * IE7 does not normalize the URL when assigned to an anchor node.  
(Apparently, it does, if one
- * uses the inner HTML approach to assign the URL as part of an HTML snippet -
- * http://stackoverflow.com/a/472729)  However, setting img[src] does 
normalize the URL.
- * Unfortunately, setting img[src] to something like "javascript:foo" on IE 
throws an exception.
- * Since the primary usage for normalizing URLs is to sanitize such URLs, we 
can't use that
- * method and IE < 8 is unsupported.

function.
- *
- * ```js
- *   // Filter registration
- *   function MyModule($provide, $filterProvider) {

- *     $filterProvider.register('greet', function(greet){
- *       // return the filter function which uses the greet service
- *       // to generate salutation
- *       return function(text) {
- *         // filters need to be forgiving so check input validity
- *         return text && greet(text) || text;
- *       };
- *     });
- *   }
- * ```
- *
- * The filter function is registered with the `$injector` under the filter 
name suffix with
- * `Filter`.
- *
- * ```js
- *   it('should be the same instance', inject(
- *     function($filterProvider) {

- * Selects a subset of items from `array` and returns it as a new array.
- *
- * @param {Array} array The source array.
- * @param {string|Object|function()} expression The predicate to be used for 
selecting items from
- *   `array`.
- *
- *   Can be one of:
- *
- *   - `string`: The string is evaluated as an expression and the resulting 
value is used for substring match against
- *     the contents of the `array`. All strings or objects with string 
properties in `array` that contain this string
- *     will be returned. The predicate can be negated by prefixing the string 
with `!`.
- *
- *   - `Object`: A pattern object can be used to filter specific properties on 
objects contained
- *     by `array`. For example `{name:"M", phone:"1"}` predicate will return 
an array of items
- *     which have property `name` containing "M" and property `phone` 
containing "1". A special
- *     property name `$` can be used (as in `{$:"text"}`) to accept a match 
against any
- *     property of the object. That's equivalent to the simple substring match 
with a `string`
- *     as described above. The predicate can be negated by prefixing the 
string with `!`.
- *     For Example `{name: "!M"}` predicate will return an array of items 
which have property `name`
- *     not containing "M".
- *
- *   - `function(value, index)`: A predicate function can be used to write 
arbitrary filters. The
- *     function is called for each element of `array`. The final result is an 
array of those
- *     elements that the predicate returned true for.
- *
- * @param {function(actual, expected)|true|undefined} comparator Comparator 
which is used in
- *     determining if the expected value (from the filter expression) and 
actual value (from
- *     the object in the array) should be considered a match.
- *
- *   Can be one of:
- *
- *   - `function(actual, expected)`:
- *     The function will be given the object value and the predicate value to 
compare and
- *     should return true if the item should be included in filtered result.
- *
- *   - `true`: A shorthand for `function(actual, expected) { return 
angular.equals(expected, actual)}`.

- *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or 
yyyyMMddTHHmmssZ). If no timezone is
- *    specified in the string input, the time is considered to be in the local 
timezone.
- * @param {string=} format Formatting rules (see Description). If not 
specified,
- *    `mediumDate` is used.
- * @param {string=} timezone Timezone to be used for formatting. Right now, 
only `'UTC'` is supported.
- *    If not specified, the timezone of the browser will be used.
- * @returns {string} Formatted string or the input if input is not recognized

-/**
- * @ngdoc filter
- * @name orderBy
- * @kind function
- *
- * @description
- * Orders a specified `array` by the `expression` predicate. It is ordered 
alphabetically
- * for strings and numerically for numbers. Note: if you notice numbers are 
not being sorted
- * correctly, make sure they are actually being saved as numbers and not 
strings.
- *
- * @param {Array} array The array to sort.
- * @param {function(*)|string|Array.<(function(*)|string)>=} expression A 
predicate to be
- *    used by the comparator to determine the order of elements.
- *
- *    Can be one of:
- *
- *    - `function`: Getter function. The result of this function will be 
sorted using the
- *      `<`, `=`, `>` operator.
- *    - `string`: An Angular expression. The result of this expression is used 
to compare elements
- *      (for example `name` to sort by a property called `name` or 
`name.substr(0, 3)` to sort by
- *      3 first characters of a property called `name`). The result of a 
constant expression
- *      is interpreted as a property name to be used in comparisons (for 
example `"special name"`
- *      to sort object by the value of their `special name` property). An 
expression can be
- *      optionally prefixed with `+` or `-` to control ascending or descending 
sort order
- *      (for example, `+name` or `-name`). If no property is provided, (e.g. 
`'+'`) then the array
- *      element itself is used to compare where sorting.
- *    - `Array`: An array of function or string predicates. The first 
predicate in the array
- *      is used for sorting, but when two items are equivalent, the next 
predicate is used.
- *
- *    If the predicate is missing or empty then it defaults to `'+'`.
- *
- * @param {boolean=} reverse Reverse the order of the array.
- * @returns {Array} Sorted copy of the source array.

- * @ngdoc directive
- * @name form
- * @restrict E
- *
- * @description
- * Directive that instantiates

- *
- * If the `name` attribute is specified, the form controller is published onto 
the current scope under
- * this name.
- *
- * # Alias: address@hidden ng.directive:ngForm `ngForm`}
- *
- * In Angular forms can be nested. This means that the outer form is valid 
when all of the child
- * forms are valid as well. However, browsers do not allow nesting of `<form>` 
elements, so
- * Angular provides the address@hidden ng.directive:ngForm `ngForm`} directive 
which behaves identically to
- * `<form>` but can be nested.  This allows you to have nested forms, which is 
very useful when
- * using Angular validation directives in forms that are dynamically generated 
using the
- * address@hidden ng.directive:ngRepeat `ngRepeat`} directive. Since you 
cannot dynamically generate the `name`
- * attribute of input elements using interpolation, you have to wrap each set 
of repeated inputs in an
- * `ngForm` directive and nest these in an outer `form` element.
- *
- *
- * # CSS classes
- *  - `ng-valid` is set if the form is valid.
- *  - `ng-invalid` is set if the form is invalid.
- *  - `ng-pristine` is set if the form is pristine.
- *  - `ng-dirty` is set if the form is dirty.
- *  - `ng-submitted` is set if the form was submitted.
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and 
removed.
- *
- *
- * # Submitting a form and preventing the default action
- *
- * Since the role of forms in client-side Angular applications is different 
than in classical
- * roundtrip apps, it is desirable for the browser not to translate the form 
submission into a full
- * page reload that sends the data to the server. Instead some javascript 
logic should be triggered
- * to handle the form submission in an application-specific way.
- *
- * For this reason, Angular prevents the default action (form submission to 
the server) unless the
- * `<form>` element has an `action` attribute specified.
- *
- * You can use one of the following two ways to specify what javascript method 
should be called when
- * a form is submitted:
- *
- * - address@hidden ng.directive:ngSubmit ngSubmit} directive on the form 
element
- * - address@hidden ng.directive:ngClick ngClick} directive on the first
-  *  button or input field of type submit (input[type=submit])
- *
- * To prevent double execution of the handler, use only one of the 
address@hidden ng.directive:ngSubmit ngSubmit}
- * or address@hidden ng.directive:ngClick ngClick} directives.
- * This is because of the following form submission rules in the HTML 
specification:
- *
- * - If a form has only one input field then hitting enter in this field 
triggers form submit
- * (`ngSubmit`)
- * - if a form has 2+ input fields and no buttons or input[type=submit] then 
hitting enter
- * doesn't trigger submit
- * - if a form has one or more input fields and one or more buttons or 
input[type=submit] then
- * hitting enter in any of the input fields will trigger the click handler on 
the *first* button or
- * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form 
(`ngSubmit`)
- *
- * Any pending `ngModelOptions` changes will take place immediately when an 
enclosing form is
- * submitted. Note that `ngClick` events will occur before the model is 
updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * ## Animation Hooks
- *
- * Animations in ngForm are triggered when any of the associated CSS classes 
are added and removed.
- * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and 
`.ng-valid` as well as any
- * other validations that are performed within the form. Animations in ngForm 
are similar to how
- * they work in ngClass and animations can be hooked into using CSS 
transitions, keyframes as well
- * as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to 
style a form element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-form {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-form.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
- *
- * @example
-    <example deps="angular-animate.js" animations="true" fixBase="true" 
module="formExample">
-      <file name="index.html">
-       <script>

-          background: transparent;
-        }
-        .my-form.ng-invalid {
-          background: red;
-        }

-   * @ngdoc input
-   * @name input[text]
-   *
-   * @description
-   * Standard HTML text input with angular data binding, inherited by most of 
the `input` elements.
-   *
-   *
-   * @param {string} ngModel Assignable angular expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control 
is published.
-   * @param {string=} required Adds `required` validation error key if the 
value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` 
validation constraint to
-   *    the element when the ngRequired expression evaluates to true. Use 
`ngRequired` instead of
-   *    `required` when you want to data-bind to the `required` attribute.
-   * @param {number=} ngMinlength Sets `minlength` validation error key if the 
value is shorter than
-   *    minlength.
-   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the 
value is longer than
-   *    maxlength. Setting the attribute to a negative or non-numeric value, 
allows view values of
-   *    any length.
-   * @param {string=} pattern Similar to `ngPattern` except that the attribute 
value is the actual string
-   *    that contains the regular expression body that will be converted to a 
regular expression
-   *    as in the ngPattern directive.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the 
ngModel value does not match
-   *    a RegExp found by evaluating the Angular expression given in the 
attribute value.
-   *    If the expression evaluates to a RegExp object then this is used 
directly.
-   *    If the expression is a string then it will be converted to a RegExp 
after wrapping it in `^` and `$`
-   *    characters. For instance, `"abc"` will be converted to `new 
RegExp('^abc$')`.
-   * @param {string=} ngChange Angular expression to be executed when input 
changes due to user
-   *    interaction with the input element.
-   * @param {boolean=} [ngTrim=true] If set to false Angular will not 
automatically trim the input.
-   *    This parameter is ignored for input[type=password] controls, which 
will never trim the
-   *    input.

-   *
-   * The timezone to be used to read/write the `Date` instance in the model

to.
- * @property {Array.<Function>} $parsers Array of functions to execute, as a 
pipeline, whenever
-       the control reads value from the DOM. The functions are called in array 
order, each passing
-       its return value through to the next. The last return value is 
forwarded to the

collection.
-
-Parsers are used to sanitize / convert the address@hidden 
ngModel.NgModelController#$viewValue
-`$viewValue`}.
-
-Returning `undefined` from a parser means a parse error occurred. In that case,
-no address@hidden ngModel.NgModelController#$validators `$validators`} will 
run and the `ngModel`
-will be set to `undefined` unless address@hidden ngModelOptions 
`ngModelOptions.allowInvalid`}
-is set to `true`. The parse error is stored in `ngModel.$error.parse`.

a pipeline, whenever
-       the model value changes. The functions are called in reverse array 
order, each passing the value through to the
-       next. The last return value is used as the actual DOM value.
-       Used to format / convert values for display in the control.
- * ```js

- *     return value.toUpperCase();
- *   }
- * }
- * ngModel.$formatters.push(formatter);
- * ```
- *
- * @property {Object.<string, function>} $validators A collection of 
validators that are applied
- *      whenever the model value changes. The key value within the object 
refers to the name of the
- *      validator while the function refers to the validation operation. The 
validation operation is
- *      provided with the model value as an argument and must return a true or 
false value depending
- *      on the response of that validation.
- *
- * ```js
- * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *   return /[0-9]+/.test(value) &&
- *          /[a-z]+/.test(value) &&

- *          /\W+/.test(value);
- * };
- * ```
- *
- * @property {Object.<string, function>} $asyncValidators A collection of 
validations that are expected to
- *      perform an asynchronous validation (e.g. a HTTP request). The 
validation function that is provided
- *      is expected to return a promise when it is run during the model 
validation process. Once the promise
- *      is delivered then the validation status will be set to true when 
fulfilled and false when rejected.
- *      When the asynchronous validators are triggered, each of the validators 
will run in parallel and the model
- *      value will only be updated once all validators have been fulfilled. As 
long as an asynchronous validator
- *      is unfulfilled, its key will be added to the controllers `$pending` 
property. Also, all asynchronous validators
- *      will only run once all synchronous validators have passed.
- *
- * Please note that if $http is used then it is important that the server 
returns a success HTTP response code
- * in order to fulfill the validation and a status level of `4xx` in order to 
reject the validation.
- *
- * ```js
- * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *
- *   // Lookup user by username
- *   return $http.get('/api/users/' + value).
- *      then(function resolved() {
- *        //username exists, this means validation fails
- *        return $q.reject('exists');
- *      }, function rejected() {
- *        //username does not exist, therefore this validation passes
- *        return true;
- *      });
- * };
- * ```
- *
- * @property {Array.<Function>} $viewChangeListeners Array of functions to 
execute whenever the
- *     view value has changed. It is called with no arguments, and its return 
value is ignored.
- *     This can be used in place of additional $watches against the model 
value.
- *
- * @property {Object} $error An object hash with all failing validator ids as 
keys.
- * @property {Object} $pending An object hash with all pending validator ids 
as keys.
- *
- * @property {boolean} $untouched True if control has not lost focus yet.
- * @property {boolean} $touched True if control has lost focus.
- * @property {boolean} $pristine True if user has not interacted with the 
control yet.
- * @property {boolean} $dirty True if user has already interacted with the 
control.
- * @property {boolean} $valid True if there is no error.
- * @property {boolean} $invalid True if at least one error on the control.
- * @property {string} $name The name attribute of the control.

- * @description
- *
- * `NgModelController` provides API for the address@hidden ngModel `ngModel`} 
directive.
- * The controller contains services for data-binding, validation, CSS updates, 
and value formatting
- * and parsing. It purposefully does not contain any logic which deals with 
DOM rendering or
- * listening to DOM events.
- * Such DOM related logic should be provided by other directives which make 
use of
- * `NgModelController` for data-binding to control elements.
- * Angular provides this DOM logic for most address@hidden input `input`} 
elements.
- * At the end of this page you can find a address@hidden 
ngModel.NgModelController#custom-control-example
- * custom control example} that uses `ngModelController` to bind to 
`contenteditable` elements.
- *
- * @example
- * ### Custom Control Example
- * This example shows how to use `NgModelController` with a custom control to 
achieve
- * data-binding. Notice how different directives (`contenteditable`, 
`ng-model`, and `required`)
- * collaborate together to achieve the desired result.
- *
- * Note that `contenteditable` is an HTML5 attribute, which tells the browser 
to let the element
- * contents be edited in place by the user.  This will not work on older 
browsers.
- *
- * We are using the address@hidden ng.service:$sce $sce} service here and 
include the address@hidden ngSanitize $sanitize}
- * module to automatically remove "bad" content like inline event listener 
(e.g. `<span onclick="...">`).
- * However, as we are using `$sce` the model can still decide to provide 
unsafe content if it marks
- * that content using the `$sce` service.
- *
- * <example name="NgModelController" module="customControl" 
deps="angular-sanitize.js">
-    <file name="style.css">
-      [contenteditable] {
-        border: 1px solid black;

-   * Update the view value.
-   *
-   * This method should be called when an input directive want to change the 
view value; typically,
-   * this is done from within a DOM event handler.
-   *
-   * For example address@hidden ng.directive:input input} calls it when the 
value of the input changes and
-   * address@hidden ng.directive:select select} calls it when an option is 
selected.
-   *
-   * If the new `value` is an object (rather than a string or a number), we 
should make a copy of the
-   * object before passing it to `$setViewValue`.  This is because `ngModel` 
does not perform a deep
-   * watch of objects, it only looks for a change of identity. If you only 
change the property of
-   * the object then ngModel will not realise that the object has changed and 
will not invoke the
-   * `$parsers` and `$validators` pipelines.
-   *
-   * For this reason, you should not change properties of the copy once it has 
been passed to
-   * `$setViewValue`. Otherwise you may cause the model value on the scope to 
change incorrectly.
-   *
-   * When this method is called, the new `value` will be staged for committing 
through the `$parsers`
-   * and `$validators` pipelines. If there are no special address@hidden 
ngModelOptions} specified then the staged
-   * value sent directly for processing, finally to be applied to 
`$modelValue` and then the
-   * **expression** specified in the `ng-model` attribute.
-   *
-   * Lastly, all the registered change listeners, in the 
`$viewChangeListeners` list, are called.
-   *
-   * In case the address@hidden ng.directive:ngModelOptions ngModelOptions} 
directive is used with `updateOn`
-   * and the `default` trigger is not listed, all those actions will remain 
pending until one of the
-   * `updateOn` events is triggered on the DOM element.
-   * All these actions will be debounced if the address@hidden 
ng.directive:ngModelOptions ngModelOptions}
-   * directive is used with a custom debounce for this particular event.

- * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, 
`ng-dirty`, `ng-pristine`, `ng-touched`, `ng-untouched`) including animations.
- * - Registering the control with its parent address@hidden ng.directive:form 
form}.
- *
- * Note: `ngModel` will try to bind to the property given by evaluating the 
expression on the
- * current scope. If the property doesn't already exist on this scope, it will 
be created
- * implicitly and added to the scope.
- *
- * For best practices on using `ngModel`, see:
- *
- *  - [Understanding 
Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
- *
- * For basic examples, how to use `ngModel`, see:
- *
- *  - address@hidden ng.directive:input input}
- *    - address@hidden input[text] text}
- *    - address@hidden input[checkbox] checkbox}
- *    - address@hidden input[radio] radio}
- *    - address@hidden input[number] number}
- *    - address@hidden input[email] email}
- *    - address@hidden input[url] url}
- *    - address@hidden input[date] date}
- *    - address@hidden input[datetime-local] datetime-local}
- *    - address@hidden input[time] time}
- *    - address@hidden input[month] month}
- *    - address@hidden input[week] week}
- *  - address@hidden ng.directive:select select}
- *  - address@hidden ng.directive:textarea textarea}
- *
- * # CSS classes
- * The following CSS classes are added and removed on the associated 
input/select/textarea element
- * depending on the validity of the model.
- *
- *  - `ng-valid`: the model is valid
- *  - `ng-invalid`: the model is invalid
- *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
- *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
- *  - `ng-pristine`: the control hasn't been interacted with yet
- *  - `ng-dirty`: the control has been interacted with
- *  - `ng-touched`: the control has been blurred
- *  - `ng-untouched`: the control hasn't been blurred
- *  - `ng-pending`: any `$asyncValidators` are unfulfilled
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and 
removed.
- *
- * ## Animation Hooks
- *
- * Animations within models are triggered when any of the associated CSS 
classes are added and removed
- * on the input element which is attached to the model. These classes are: 
`.ng-pristine`, `.ng-dirty`,
- * `.ng-invalid` and `.ng-valid` as well as any other validations that are 
performed on the model itself.
- * The animations that are triggered within ngModel are similar to how they 
work in ngClass and
- * animations can be hooked into using CSS transitions, keyframes as well as 
JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to 
style an input element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-input {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-input.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
- *
- * @example
- * <example deps="angular-animate.js" animations="true" fixBase="true" 
module="inputExample">
-     <file name="index.html">
-       <script>
-        angular.module('inputExample', [])
-          .controller('ExampleController', ['$scope', function($scope) {
-            $scope.val = '1';
-          }]);
-       </script>
-       <style>
-         .my-input {
-           -webkit-transition:all linear 0.5s;
-           transition:all linear 0.5s;
-           background: transparent;
-         }
-         .my-input.ng-invalid {
-           color:white;
-           background: red;
-         }
-       </style>
-       Update input to see transitions when valid/invalid.
-       Integer is a valid value.
-       <form name="testForm" ng-controller="ExampleController">
-         <input ng-model="val" ng-pattern="/^\d+$/" name="anim" 
class="my-input" />
-       </form>
-     </file>
- * </example>
- *
- * ## Binding to a getter/setter
- *
- * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A 
getter/setter is a
- * function that returns a representation of the model when called with zero 
arguments, and sets
- * the internal state of a model when called with an argument. It's sometimes 
useful to use this
- * for models that have an internal representation that's different than what 
the model exposes
- * to the view.
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's best to keep getters fast because Angular is likely 
to call them more
- * frequently than other parts of your code.
- * </div>
- *
- * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` 
to an element that
- * has `ng-model` attached to it. You can also add `ng-model-options="{ 
getterSetter: true }"` to
- * a `<form>`, which will enable this behavior for all `<input>`s within it. 
See
- * address@hidden ng.directive:ngModelOptions `ngModelOptions`} for more.
- *
- * The following example shows how to use `ngModel` with a getter/setter:
- *
- * @example
- * <example name="ngModel-getter-setter" module="getterSetterExample">
-     <file name="index.html">
-       <div ng-controller="ExampleController">
-         <form name="userForm">
-           Name:
-           <input type="text" name="userName"
-                  ng-model="user.name"
-                  ng-model-options="{ getterSetter: true }" />
-         </form>
-         <pre>user.name = <span ng-bind="user.name()"></span></pre>
-       </div>
-     </file>
-     <file name="app.js">
-       angular.module('getterSetterExample', [])
-         .controller('ExampleController', ['$scope', function($scope) {
-           var _name = 'Brian';
-           $scope.user = {
-             name: function(newName) {
-               if (angular.isDefined(newName)) {
-                 _name = newName;
-               }
-               return _name;
-             }
-           };

-/**
- * @ngdoc directive
- * @name ngList
- *
- * @description
- * Text input that converts between a delimited string and an array of 
strings. The default
- * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. 
You can specify a custom
- * delimiter as the value of the `ngList` attribute - for example, `ng-list=" 
| "`.
- *
- * The behaviour of the directive is affected by the use of the `ngTrim` 
attribute.
- * * If `ngTrim` is set to `"false"` then whitespace around both the separator 
and each
- *   list item is respected. This implies that the user of the directive is 
responsible for
- *   dealing with whitespace but also allows you to use whitespace as a 
delimiter, such as a
- *   tab or newline character.
- * * Otherwise whitespace around the delimiter is ignored when splitting 
(although it is respected
- *   when joining the list items back together) and whitespace around each 
list item is stripped
- *   before it is added to the model.

-/**
- * @ngdoc directive
- * @name ngModelOptions
- *
- * @description
- * Allows tuning how model updates are done. Using `ngModelOptions` you can 
specify a custom list of
- * events that will trigger a model update and/or a debouncing delay so that 
the actual update only
- * takes place when a timer expires; this timer will be reset after another 
change takes place.
- *
- * Given the nature of `ngModelOptions`, the value displayed inside input 
fields in the view might
- * be different than the value in the actual model. This means that if you 
update the model you
- * should also invoke address@hidden ngModel.NgModelController 
`$rollbackViewValue`} on the relevant input field in
- * order to make sure it is synchronized with the model and that any debounced 
action is canceled.
- *
- * The easiest way to reference the control's address@hidden 
ngModel.NgModelController `$rollbackViewValue`}
- * method is by making sure the input is placed inside a form that has a 
`name` attribute. This is
- * important because `form` controllers are published to the related scope 
under the name in their
- * `name` attribute.
- *
- * Any pending changes will take place immediately when an enclosing form is 
submitted via the
- * `submit` event. Note that `ngClick` events will occur before the model is 
updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * `ngModelOptions` has an effect on the element it's declared on and its 
descendants.
- *
- * @param {Object} ngModelOptions options to apply to the current model. Valid 
keys are:
- *   - `updateOn`: string specifying which event should the input be bound to. 
You can set several
- *     events using an space delimited list. There is a special event called 
`default` that
- *     matches the default events belonging of the control.
- *   - `debounce`: integer value which contains the debounce model update 
value in milliseconds. A
- *     value of 0 triggers an immediate update. If an object is supplied 
instead, you can specify a
- *     custom value for each event. For example:
- *     `ng-model-options="{ updateOn: 'default blur', debounce: {'default': 
500, 'blur': 0} }"`
- *   - `allowInvalid`: boolean value which indicates that the model can be set 
with values that did
- *     not validate correctly instead of the default behavior of setting the 
model to undefined.
- *   - `getterSetter`: boolean value which determines whether or not to treat 
functions bound to
-       `ngModel` as getters/setters.
- *   - `timezone`: Defines the timezone to be used to read/write the `Date` 
instance in the model for
- *     `<input type="date">`, `<input type="time">`, ... . Right now, the only 
supported value is `'UTC'`,
- *     otherwise the default timezone of the browser will be used.
- *
- * @example
-
-  The following example shows how to override immediate updates. Changes on 
the inputs within the
-  form will update the model only when the control loses focus (blur event). 
If `escape` key is
-  pressed while the input field is focused, the value is reset to the value in 
the current model.

-/**
- * @ngdoc directive
- * @name ngBind
- * @restrict AC
- *
- * @description
- * The `ngBind` attribute tells Angular to replace the text content of the 
specified HTML element
- * with the value of a given expression, and to update the text content when 
the value of that
- * expression changes.
- *
- * Typically, you don't use `ngBind` directly, but instead you use the double 
curly markup like
- * `{{ expression }}` which is similar but less verbose.
- *
- * It is preferable to use `ngBind` instead of `{{ expression }}` if a 
template is momentarily
- * displayed by the browser in its raw state before Angular compiles it. Since 
`ngBind` is an
- * element attribute, it makes the bindings invisible to the user while the 
page is loading.
- *
- * An alternative solution to this problem would be using the
- * address@hidden ng.directive:ngCloak ngCloak} directive.
- *
- *
- * @element ANY
- * @param {expression} ngBind address@hidden guide/expression Expression} to

changes instantly.

- * @ngdoc directive
- * @name ngClass
- * @restrict AC
- *
- * @description
- * The `ngClass` directive allows you to dynamically set CSS classes on an 
HTML element by databinding
- * an expression that represents all classes to be added.
- *
- * The directive operates in three different ways, depending on which of three 
types the expression
- * evaluates to:
- *
- * 1. If the expression evaluates to a string, the string should be one or 
more space-delimited class
- * names.
- *
- * 2. If the expression evaluates to an array, each element of the array 
should be a string that is
- * one or more space-delimited class names.
- *
- * 3. If the expression evaluates to an object, then for each key-value pair 
of the
- * object with a truthy value the corresponding key is used as a class name.
- *
- * The directive won't add duplicate classes if a particular class was already 
set.
- *
- * When the expression changes, the previously added classes are removed and 
only then the
- * new classes are added.
- *
- * @animations
- * add - happens just before the class is applied to the element
- * remove - happens just before the class is removed from the element
- *
- * @element ANY
- * @param {expression} ngClass address@hidden guide/expression Expression} to 
eval. The result
- *   of the evaluation can be a string representing space delimited class
- *   names, an array, or a map of class names to boolean values. In the case 
of a map, the
- *   names of the properties whose values are truthy will be added as css 
classes to the
- *   element.
- *
- * @example Example that demonstrates basic bindings via ngClass directive.
-   <example>
-     <file name="index.html">
-       <p ng-class="{strike: deleted, bold: important, red: error}">Map Syntax

-   ## Animations
-
-   The example below demonstrates how to perform animations using ngClass.
-
-   <example module="ngAnimate" deps="angular-animate.js" animations="true">
-     <file name="index.html">
-      <input id="setbtn" type="button" value="set" ng-click="myVar='my-class'">
-      <input id="clearbtn" type="button" value="clear" ng-click="myVar=''">
-      <br>
-      <span class="base-class" ng-class="myVar">Sample Text</span>
-     </file>
-     <file name="style.css">
-       .base-class {
-         -webkit-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
-         transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
-       }
-
-       .base-class.my-class {
-         color: red;
-         font-size:3em;
-       }
-     </file>
-     <file name="protractor.js" type="protractor">
-       it('should check ng-class', function() {
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-
-         element(by.id('setbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).
-           toMatch(/my-class/);
-
-         element(by.id('clearbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-       });
-     </file>
-   </example>
-
-
-   ## ngClass and pre-existing CSS3 Transitions/Animations
-   The ngClass directive still supports CSS3 Transitions/Animations even if 
they do not follow the ngAnimate CSS naming structure.
-   Upon animation ngAnimate will apply supplementary CSS classes to track the 
start and end of an animation, but this will not hinder
-   any pre-existing CSS transitions already on the element. To get an idea of 
what happens during a class-based animation, be sure
-   to view the step by step details of address@hidden ng.$animate#addClass 
$animate.addClass} and
-   address@hidden ng.$animate#removeClass $animate.removeClass}.

-/**
- * @ngdoc directive
- * @name ngCloak
- * @restrict AC
- *
- * @description
- * The `ngCloak` directive is used to prevent the Angular html template from 
being briefly
- * displayed by the browser in its raw (uncompiled) form while your 
application is loading. Use this
- * directive to avoid the undesirable flicker effect caused by the html 
template display.
- *
- * The directive can be applied to the `<body>` element, but the preferred 
usage is to apply
- * multiple `ngCloak` directives to small portions of the page to permit 
progressive rendering
- * of the browser view.
- *
- * `ngCloak` works in cooperation with the following css rule embedded within 
`angular.js` and
- * `angular.min.js`.
- * For CSP mode please add `angular-csp.css` to your html file (see 
address@hidden ng.directive:ngCsp ngCsp}).
- *
- * ```css
- * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, 
.x-ng-cloak {
- *   display: none !important;
- * }
- * ```
- *
- * When this css rule is loaded by the browser, all html elements (including 
their children) that
- * are tagged with the `ngCloak` directive are hidden. When Angular encounters 
this directive
- * during the compilation of the template it deletes the `ngCloak` element 
attribute, making
- * the compiled element visible.
- *
- * For the best result, the `angular.js` script must be loaded in the head 
section of the html
- * document; alternatively, the css rule above must be included in the 
external stylesheet of the
- * application.
- *
- * Legacy browsers, like IE7, do not provide attribute selector support (added 
in CSS 2.1) so they
- * cannot match the `[ng\:cloak]` selector. To work around this limitation, 
you must add the css
- * class `ng-cloak` in addition to the `ngCloak` directive as shown in the 
example below.
- *
- * @element ANY
- *
- * @example
-   <example>
-     <file name="index.html">

-/**
- * @ngdoc directive
- * @name ngController
- *
- * @description
- * The `ngController` directive attaches a controller class to the view. This 
is a key aspect of how angular
- * supports the principles behind the Model-View-Controller design pattern.
- *
- * MVC components in angular:
- *
- * * Model — Models are the properties of a scope; scopes are attached to the 
DOM where scope properties
- *   are accessed through bindings.
- * * View — The template (HTML with data bindings) that is rendered into the 
View.
- * * Controller — The `ngController` directive specifies a Controller class; 
the class contains business
- *   logic behind the application to decorate the scope with functions and 
values
- *
- * Note that you can also attach controllers to the DOM by declaring it in a 
route definition
- * via the address@hidden ngRoute.$route $route} service. A common mistake is 
to declare the controller
- * again using `ng-controller` in the template itself.  This will cause the 
controller to be attached
- * and executed twice.
- *
- * @element ANY
- * @scope
- * @priority 500
- * @param {expression} ngController Name of a constructor function registered 
with the current
- * address@hidden ng.$controllerProvider $controllerProvider} or an 
address@hidden guide/expression expression}
- * that on the current scope evaluates to a constructor function.
- *
- * The controller instance can be published into a scope property by specifying
- * `ng-controller="as propertyName"`.
- *
- * If the current `$controllerProvider` is configured to use globals (via
- * address@hidden ng.$controllerProvider#allowGlobals 
`$controllerProvider.allowGlobals()` }), this may
- * also be the name of a globally accessible constructor function (not 
recommended).
- *
- * @example
- * Here is a simple form for editing user contact information. Adding, 
removing, clearing, and
- * greeting are methods declared on the controller (see source tab). These 
methods can
- * easily be called from the angular markup. Any changes to the data are 
automatically reflected
- * in the View without the need for a manual update.
- *
- * Two different declaration styles are included below:
- *
- * * one binds methods and properties directly onto the controller using 
`this`:
- * `ng-controller="SettingsController1 as settings"`
- * * one injects `$scope` into the controller:
- * `ng-controller="SettingsController2"`
- *
- * The second option is more common in the Angular community, and is generally 
used in boilerplates
- * and in this guide. However, there are advantages to binding properties 
directly to the controller
- * and avoiding scope.
- *
- * * Using `controller as` makes it obvious which controller you are accessing 
in the template when
- * multiple controllers apply to an element.
- * * If you are writing your controllers as classes you have easier access to 
the properties and
- * methods, which will appear on the scope, from inside the controller code.
- * * Since there is always a `.` in the bindings, you don't have to worry 
about prototypal
- * inheritance masking primitives.
- *
- * This example demonstrates the `controller as` syntax.
- *
- * <example name="ngControllerAs" module="controllerAsExample">
- *   <file name="index.html">
- *    <div id="ctrl-as-exmpl" ng-controller="SettingsController1 as settings">

-/**
- * @ngdoc directive
- * @name ngCsp
- *
- * @element html
- * @description
- * Enables [CSP (Content Security 
Policy)](https://developer.mozilla.org/en/Security/CSP) support.
- *
- * This is necessary when developing things like Google Chrome Extensions or 
Universal Windows Apps.
- *
- * CSP forbids apps to use `eval` or `Function(string)` generated functions 
(among other things).
- * For Angular to be CSP compatible there are only two things that we need to 
do differently:
- *
- * - don't use `Function` constructor to generate optimized value getters
- * - don't inject custom stylesheet into the document
- *
- * AngularJS uses `Function(string)` generated functions as a speed 
optimization. Applying the `ngCsp`
- * directive will cause Angular to use CSP compatibility mode. When this mode 
is on AngularJS will
- * evaluate all expressions up to 30% slower than in non-CSP mode, but no 
security violations will
- * be raised.
- *
- * CSP forbids JavaScript to inline stylesheet rules. In non CSP mode Angular 
automatically
- * includes some CSS rules (e.g. address@hidden ng.directive:ngCloak ngCloak}).
- * To make those directives work in CSP mode, include the `angular-csp.css` 
manually.
- *
- * Angular tries to autodetect if CSP is active and automatically turn on the 
CSP-safe mode. This
- * autodetection however triggers a CSP error to be logged in the console:
- *
- * ```
- * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an 
allowed source of
- * script in the following Content Security Policy directive: "default-src 
'self'". Note that
- * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
- * ```
- *
- * This error is harmless but annoying. To prevent the error from showing up, 
put the `ngCsp`
- * directive on the root element of the application or on the `angular.js` 
script tag, whichever
- * appears first in the html document.
- *
- * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` 
attribute form.*
- *
- * @example
- * This example shows how to apply the `ngCsp` directive to the `html` tag.
-   ```html
-     <!doctype html>
-     <html ng-app ng-csp>
-     ...
-     ...
-     </html>
-   ```
-  * @example
-      // Note: the suffix `.csp` in the example name triggers
-      // csp mode in our http server!
-      <example name="example.csp" module="cspExample" ng-csp="true">

-/**
- * @ngdoc directive
- * @name ngIf
- * @restrict A
- *
- * @description
- * The `ngIf` directive removes or recreates a portion of the DOM tree based 
on an
- * {expression}. If the expression assigned to `ngIf` evaluates to a false
- * value then the element is removed from the DOM, otherwise a clone of the
- * element is reinserted into the DOM.
- *
- * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes 
and recreates the
- * element in the DOM rather than changing its visibility via the `display` 
css property.  A common
- * case when this difference is significant is when using css selectors that 
rely on an element's
- * position within the DOM, such as the `:first-child` or `:last-child` 
pseudo-classes.
- *
- * Note that when an element is removed using `ngIf` its scope is destroyed 
and a new scope
- * is created when the element is restored.  The scope created within `ngIf` 
inherits from
- * its parent scope using
- * [prototypal 
inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
- * An important implication of this is if `ngModel` is used within `ngIf` to 
bind to
- * a javascript primitive defined in the parent scope. In this case any 
modifications made to the
- * variable within the child scope will override (hide) the value in the 
parent scope.
- *
- * Also, `ngIf` recreates elements using their compiled state. An example of 
this behavior
- * is if an element's class attribute is directly modified after it's 
compiled, using something like
- * jQuery's `.addClass()` method, and the element is later removed. When 
`ngIf` recreates the element
- * the added class will be lost because the original compiled state is used to 
regenerate the element.
- *
- * Additionally, you can provide animations via the `ngAnimate` module to 
animate the `enter`
- * and `leave` effects.
- *
- * @animations
- * enter - happens just after the `ngIf` contents change and a new DOM element 
is created and injected into the `ngIf` container
- * leave - happens just before the `ngIf` contents are removed from the DOM
- *
- * @element ANY
- * @scope
- * @priority 600
- * @param {expression} ngIf If the address@hidden guide/expression expression} 
is falsy then
- *     the element is removed from the DOM tree. If it is truthy a copy of the 
compiled
- *     element is added to the DOM tree.
- *
- * @example
-  <example module="ngAnimate" deps="angular-animate.js" animations="true">

-/**
- * @ngdoc directive
- * @name ngPluralize
- * @restrict EA
- *
- * @description
- * `ngPluralize` is a directive that displays messages according to en-US 
localization rules.
- * These rules are bundled with angular.js, but can be overridden
- * (see address@hidden guide/i18n Angular i18n} dev guide). You configure 
ngPluralize directive
- * by specifying the mappings between
- * [plural 
categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
- * and the strings to be displayed.
- *
- * # Plural categories and explicit number rules
- * There are two
- * [plural 
categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
- * in Angular's default en-US locale: "one" and "other".
- *
- * While a plural category may match many numbers (for example, in en-US 
locale, "other" can match
- * any number that is not 1), an explicit number rule can only match one 
number. For example, the
- * explicit number rule for "3" matches the number 3. There are examples of 
plural categories
- * and explicit number rules throughout the rest of this documentation.
- *
- * # Configuring ngPluralize
- * You configure ngPluralize by providing 2 attributes: `count` and `when`.
- * You can also provide an optional attribute, `offset`.
- *
- * The value of the `count` attribute can be either a string or an 
address@hidden guide/expression
- * Angular expression}; these are evaluated on the current scope for its bound 
value.
- *
- * The `when` attribute specifies the mappings between plural categories and 
the actual
- * string to be displayed. The value of the attribute should be a JSON object.
- *
- * The following example shows how to configure ngPluralize:
- *
- * ```html
- * <ng-pluralize count="personCount"
-                 when="{'0': 'Nobody is viewing.',
- *                      'one': '1 person is viewing.',
- *                      'other': '{} people are viewing.'}">
- * </ng-pluralize>
- *```
- *
- * In the example, `"0: Nobody is viewing."` is an explicit number rule. If 
you did not
- * specify this rule, 0 would be matched to the "other" category and "0 people 
are viewing"
- * would be shown instead of "Nobody is viewing". You can specify an explicit 
number rule for
- * other numbers, for example 12, so that instead of showing "12 people are 
viewing", you can
- * show "a dozen people are viewing".
- *
- * You can use a set of closed braces (`{}`) as a placeholder for the number 
that you want substituted
- * into pluralized strings. In the previous example, Angular will replace `{}` 
with
- * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a 
placeholder
- * for <span ng-non-bindable>{{numberExpression}}</span>.
- *
- * # Configuring ngPluralize with offset
- * The `offset` attribute allows further customization of pluralized text, 
which can result in
- * a better user experience. For example, instead of the message "4 people are 
viewing this document",
- * you might display "John, Kate and 2 others are viewing this document".
- * The offset attribute allows you to offset a number by any desired value.
- * Let's take a look at an example:
- *
- * ```html
- * <ng-pluralize count="personCount" offset=2
- *               when="{'0': 'Nobody is viewing.',
- *                      '1': '{{person1}} is viewing.',
- *                      '2': '{{person1}} and {{person2}} are viewing.',
- *                      'one': '{{person1}}, {{person2}} and one other person 
are viewing.',
- *                      'other': '{{person1}}, {{person2}} and {} other people 
are viewing.'}">
- * </ng-pluralize>
- * ```
- *
- * Notice that we are still using two plural categories(one, other), but we 
added
- * three explicit number rules 0, 1 and 2.
- * When one person, perhaps John, views the document, "John is viewing" will 
be shown.
- * When three people view the document, no explicit number rule is found, so
- * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural 
category.
- * In this case, plural category 'one' is matched and "John, Mary and one 
other person are viewing"
- * is shown.
- *
- * Note that when you specify offsets, you must provide explicit number rules 
for
- * numbers from 0 up to and including the offset. If you use an offset of 3, 
for example,
- * you must provide explicit number rules for 0, 1, 2 and 3. You must also 
provide plural strings for
- * plural categories "one" and "other".
- *
- * @param {string|expression} count The variable to be bound to.
- * @param {string} when The mapping between plural category to its 
corresponding strings.
- * @param {number=} offset Offset to deduct from the total number.
- *
- * @example
-    <example module="pluralizeExample">
-      <file name="index.html">
-        <script>
-          angular.module('pluralizeExample', [])
-            .controller('ExampleController', ['$scope', function($scope) {
-              $scope.person1 = 'Igor';
-              $scope.person2 = 'Misko';
-              $scope.personCount = 1;
-            }]);
-        </script>
-        <div ng-controller="ExampleController">
-          Person 1:<input type="text" ng-model="person1" value="Igor" /><br/>
-          Person 2:<input type="text" ng-model="person2" value="Misko" /><br/>
-          Number of People:<input type="text" ng-model="personCount" value="1"

- * To repeat a series of elements instead of just one parent element, ngRepeat 
(as well as other ng directives) supports extending
- * the range of the repeater by defining explicit start and end points by 
using **ng-repeat-start** and **ng-repeat-end** respectively.
- * The **ng-repeat-start** directive works the same as **ng-repeat**, but will 
repeat all the HTML code (including the tag it's defined on)
- * up to and including the ending HTML tag where **ng-repeat-end** is placed.
- *
- * The example below makes use of this feature:
- * ```html
- *   <header ng-repeat-start="item in items">
- *     Header {{ item }}
- *   </header>
- *   <div class="body">
- *     Body {{ item }}
- *   </div>
- *   <footer ng-repeat-end>
- *     Footer {{ item }}
- *   </footer>
- * ```
- *
- * And with an input of address@hidden ['A','B']} for the items variable in 
the example above, the output will evaluate to:
- * ```html
- *   <header>
- *     Header A
- *   </header>
- *   <div class="body">
- *     Body A
- *   </div>
- *   <footer>
- *     Footer A
- *   </footer>
- *   <header>
- *     Header B
- *   </header>
- *   <div class="body">
- *     Body B
- *   </div>
- *   <footer>
- *     Footer B
- *   </footer>
- * ```
- *
- * The custom start and end points for ngRepeat also support all other HTML 
directive syntax flavors provided in AngularJS (such
- * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
- *
- * @animations
- * **.enter** - when a new item is added to the list or when an item is 
revealed after a filter
- *
- * **.leave** - when an item is removed from the list or when an item is 
filtered out
- *
- * **.move** - when an adjacent item is filtered out causing a reorder or when 
the item contents are reordered
- *
- * @element ANY
- * @scope
- * @priority 1000
- * @param {repeat_expression} ngRepeat The expression indicating how to 
enumerate a collection. These
- *   formats are currently supported:
- *
- *   * `variable in expression` – where variable is the user defined loop 
variable and `expression`
- *     is a scope expression giving the collection to enumerate.
- *
- *     For example: `album in artist.albums`.
- *
- *   * `(key, value) in expression` – where `key` and `value` can be any user 
defined identifiers,
- *     and `expression` is the scope expression giving the collection to 
enumerate.
- *
- *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
- *
- *   * `variable in expression track by tracking_expression` – You can also 
provide an optional tracking function
- *     which can be used to associate the objects in the collection with the 
DOM elements. If no tracking function
- *     is specified the ng-repeat associates elements by identity in the 
collection. It is an error to have
- *     more than one tracking function to resolve to the same key. (This would 
mean that two distinct objects are
- *     mapped to the same DOM element, which is not possible.)  Filters should 
be applied to the expression,
- *     before specifying a tracking expression.
- *
- *     For example: `item in items` is equivalent to `item in items track by 
$id(item)`. This implies that the DOM elements
- *     will be associated by item identity in the array.
- *
- *     For example: `item in items track by $id(item)`. A built in `$id()` 
function can be used to assign a unique
- *     `$$hashKey` property to each item in the array. This property is then 
used as a key to associated DOM elements
- *     with the corresponding item in the array by identity. Moving the same 
object in array would move the DOM
- *     element in the same way in the DOM.
- *
- *     For example: `item in items track by item.id` is a typical pattern when 
the items come from the database. In this
- *     case the object identity does not matter. Two objects are considered 
equivalent as long as their `id`
- *     property is same.
- *
- *     For example: `item in items | filter:searchText track by item.id` is a 
pattern that might be used to apply a filter
- *     to items in conjunction with a tracking expression.
- *
- *   * `variable in expression as alias_expression` – You can also provide an 
optional alias expression which will then store the
- *     intermediate results of the repeater after the filters have been 
applied. Typically this is used to render a special message
- *     when a filter is active on the repeater, but the filtered result set is 
empty.
- *
- *     For example: `item in items | filter:x as results` will store the 
fragment of the repeated items as `results`, but only after
- *     the items have been processed through the filter.
- *
- * @example
- * This example initializes the scope to a list of names and
- * then uses `ngRepeat` to display every person:

removing or adding
- * the `.ng-hide` CSS class onto the element. The `.ng-hide` CSS class is 
predefined

- * For CSP mode please add `angular-csp.css` to your html file (see 
address@hidden ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * <!-- when $scope.myValue is truthy (element is visible) -->
- * <div ng-show="myValue"></div>
- *
- * <!-- when $scope.myValue is falsy (element is hidden) -->
- * <div ng-show="myValue" class="ng-hide"></div>
- * ```
- *
- * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` 
CSS class is added to the class
- * attribute on the element causing it to become hidden. When truthy, the 
`.ng-hide` CSS class is removed
- * from the element causing the element not to appear hidden.
- *
- * ## Why is !important used?
- *
- * You may be wondering why !important is used for the `.ng-hide` CSS class. 
This is because the `.ng-hide` selector
- * can be easily overridden by heavier selectors. For example, something as 
simple
- * as changing the display style on a HTML list item would make hidden 
elements appear visible.
- * This also becomes a bigger issue when dealing with CSS frameworks.
- *
- * By using !important, the show and hide behavior will work as expected 
despite any clash between CSS selector
- * specificity (when !important isn't used with any conflicting styles). If a 
developer chooses to override the
- * styling to change how to hide an element then it is just a matter of using 
!important in their own CSS code.
- *
- * ### Overriding `.ng-hide`
- *
- * By default, the `.ng-hide` class will style the element with `display: 
none!important`. If you wish to change
- * the hide behavior with ngShow/ngHide then this can be achieved by restating 
the styles for the `.ng-hide`
- * class in CSS:
- *
- * ```css
- * .ng-hide {
- *   /&#42; this is just another form of hiding an element &#42;/
- *   display: block!important;
- *   position: absolute;
- *   top: -9999px;
- *   left: -9999px;
- * }
- * ```
- *
- * By default you don't need to override in CSS anything and the animations 
will work around the display style.
- *
- * ## A note about animations with `ngShow`
- *
- * Animations in ngShow/ngHide work with the show and hide events that are 
triggered when the directive expression
- * is true and false. This system works like the animation system present with 
ngClass except that
- * you must also include the !important flag to override the display property
- * so that you can perform an animation when the element is hidden during the 
time of the animation.
- *
- * ```css
- * //
- * //a working example can be found at the bottom of this page
- * //
- * .my-element.ng-hide-add, .my-element.ng-hide-remove {
- *   /&#42; this is required as of 1.3x to properly
- *      apply all styling in a show/hide animation &#42;/
- *   transition: 0s linear all;
- * }
- *
- * .my-element.ng-hide-add-active,
- * .my-element.ng-hide-remove-active {
- *   /&#42; the transition is defined in the active class &#42;/
- *   transition: 1s linear all;
- * }
- *
- * .my-element.ng-hide-add { ... }
- * .my-element.ng-hide-add.ng-hide-add-active { ... }
- * .my-element.ng-hide-remove { ... }
- * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
- * ```
- *
- * Keep in mind that, as of AngularJS version 1.3.0-beta.11, there is no need 
to change the display
- * property to block during animation states--ngAnimate will handle the style 
toggling automatically for you.
- *
- * @animations
- * addClass: `.ng-hide` - happens after the `ngShow` expression evaluates to a

- * @ngdoc directive
- * @name ngHide
- *
- * @description
- * The `ngHide` directive shows or hides the given HTML element based on the 
expression
- * provided to the `ngHide` attribute. The element is shown or hidden by 
removing or adding
- * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is 
predefined
- * in AngularJS and sets the display style to none (using an !important flag).
- * For CSP mode please add `angular-csp.css` to your html file (see 
address@hidden ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * <!-- when $scope.myValue is truthy (element is hidden) -->
- * <div ng-hide="myValue" class="ng-hide"></div>
- *
- * <!-- when $scope.myValue is falsy (element is visible) -->
- * <div ng-hide="myValue"></div>
- * ```
- *
- * When the `ngHide` expression evaluates to a truthy value then the 
`.ng-hide` CSS class is added to the class
- * attribute on the element causing it to become hidden. When falsy, the 
`.ng-hide` CSS class is removed
- * from the element causing the element not to appear hidden.

-/**
- * @ngdoc directive
- * @name ngSwitch
- * @restrict EA
- *
- * @description
- * The `ngSwitch` directive is used to conditionally swap DOM structure on 
your template based on a scope expression.
- * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` 
directives will be preserved at the location
- * as specified in the template.
- *
- * The directive itself works similar to ngInclude, however, instead of 
downloading template code (or loading it
- * from the template cache), `ngSwitch` simply chooses one of the nested 
elements and makes it visible based on which element
- * matches the value obtained from the evaluated expression. In other words, 
you define a container element
- * (where you place the directive), place an expression on the **`on="..."` 
attribute**
- * (or the **`ng-switch="..."` attribute**), define any inner elements inside 
of the directive and place
- * a when attribute per element. The when attribute is used to inform ngSwitch 
which element to display when the on
- * expression is evaluated. If a matching expression is not found via a when 
attribute then an element with the default
- * attribute is displayed.
- *
- * <div class="alert alert-info">
- * Be aware that the attribute values to match against cannot be expressions. 
They are interpreted
- * as literal string values to match against.
- * For example, **`ng-switch-when="someVal"`** will match against the string 
`"someVal"` not against the
- * value of the expression `$scope.someVal`.
- * </div>
-
- * @animations
- * enter - happens after the ngSwitch contents change and the matched child 
element is placed inside the container
- * leave - happens just after the ngSwitch contents change and just before the 
former contents are removed from the DOM
- *
- * @usage
- *
- * ```
- * <ANY ng-switch="expression">
- *   <ANY ng-switch-when="matchValue1">...</ANY>
- *   <ANY ng-switch-when="matchValue2">...</ANY>
- *   <ANY ng-switch-default>...</ANY>
- * </ANY>
- * ```
- *
- *
- * @scope
- * @priority 1200
- * @param {*} ngSwitch|on expression to match against <tt>ng-switch-when</tt>.
- * On child elements add:
- *
- * * `ngSwitchWhen`: the case statement to match against. If match then this
- *   case will be displayed. If the same match appears multiple times, all the
- *   elements will be displayed.
- * * `ngSwitchDefault`: the default case when no other case match. If there
- *   are multiple default cases, all of them will be displayed when no other
- *   case match.

- * @ngdoc directive
- * @name select
- * @restrict E
- *
- * @description
- * HTML `SELECT` element with angular data-binding.
- *
- * # `ngOptions`
- *
- * The `ngOptions` attribute can be used to dynamically generate a list of 
`<option>`
- * elements for the `<select>` element using the array or object obtained by 
evaluating the
- * `ngOptions` comprehension_expression.
- *
- * In many cases, `ngRepeat` can be used on `<option>` elements instead of 
`ngOptions` to achieve a
- * similar result. However, the `ngOptions` provides some benefits such as 
reducing memory and
- * increasing speed by not creating a new scope for each repeated instance, as 
well as providing
- * more flexibility in how the `select`'s model is assigned via `select as`. 
`ngOptions` should be
- * used when the `select` model needs to be bound to a non-string value. This 
is because an option
- * element can only be bound to string values at present.
- *
- * When an item in the `<select>` menu is selected, the array element or 
object property
- * represented by the selected option will be bound to the model identified by 
the `ngModel`
- * directive.
- *
- * Optionally, a single hard-coded `<option>` element, with the value set to 
an empty string, can
- * be nested into the `<select>` element. This element will then represent the 
`null` or "not selected"
- * option. See example below for demonstration.
- *
- * <div class="alert alert-warning">
- * **Note:** `ngModel` compares by reference, not value. This is important 
when binding to an
- * array of objects. See an example [in this 
jsfiddle](http://jsfiddle.net/qWzTb/).
- * </div>
- *
- * ## `select as`
- *
- * Using `select as` will bind the result of the `select as` expression to the 
model, but
- * the value of the `<select>` and `<option>` html elements will be either the 
index (for array data sources)
- * or property name (for object data sources) of the value within the 
collection. If a `track by` expression
- * is used, the result of that expression will be set as the value of the 
`option` and `select` elements.
- *
- * ### `select as` with `trackexpr`
- *
- * Using `select as` together with `trackexpr` is not recommended. Reasoning:
- *
- * - Example: &lt;select ng-options="item.subItem as item.label for item in 
values track by item.id" ng-model="selected"&gt;
- *   values: [{id: 1, label: 'aLabel', subItem: {name: 'aSubItem'}}, {id: 2, 
label: 'bLabel', subItem: {name: 'bSubItem'}}],
- *   $scope.selected = {name: 'aSubItem'};
- * - track by is always applied to `value`, with the purpose of preserving the 
selection,
- *   (to `item` in this case)
- * - to calculate whether an item is selected we do the following:
- *   1. apply `track by` to the values in the array, e.g.
- *      In the example: [1,2]
- *   2. apply `track by` to the already selected value in `ngModel`:
- *      In the example: this is not possible, as `track by` refers to 
`item.id`, but the selected
- *      value from `ngModel` is `{name: aSubItem}`.
- *
- * @param {string} ngModel Assignable angular expression to data-bind to.
- * @param {string=} name Property name of the form under which the control is 
published.
- * @param {string=} required The control is considered valid only if value is 
entered.
- * @param {string=} ngRequired Adds `required` attribute and `required` 
validation constraint to
- *    the element when the ngRequired expression evaluates to true. Use 
`ngRequired` instead of
- *    `required` when you want to data-bind to the `required` attribute.
- * @param {comprehension_expression=} ngOptions in one of the following forms:
- *
- *   * for array data sources:
- *     * `label` **`for`** `value` **`in`** `array`
- *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
- *     * `label`  **`group by`** `group` **`for`** `value` **`in`** `array`
- *     * `select` **`as`** `label` **`group by`** `group` **`for`** `value` 
**`in`** `array` **`track by`** `trackexpr`
- *   * for object data sources:
- *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** 
`object`
- *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) 
in`** `object`
- *     * `select` **`as`** `label` **`group by`** `group`
- *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
- *
- * Where:
- *
- *   * `array` / `object`: an expression which evaluates to an array / object 
to iterate over.
- *   * `value`: local variable which will refer to each item in the `array` or 
each property value
- *      of `object` during iteration.
- *   * `key`: local variable which will refer to a property name in `object` 
during iteration.
- *   * `label`: The result of this expression will be the label for `<option>` 
element. The
- *     `expression` will most likely refer to the `value` variable (e.g. 
`value.propertyName`).
- *   * `select`: The result of this expression will be bound to the model of 
the parent `<select>`
- *      element. If not specified, `select` expression will default to `value`.
- *   * `group`: The result of this expression will be used to group options 
using the `<optgroup>`
- *      DOM element.
- *   * `trackexpr`: Used when working with an array of objects. The result of 
this expression will be
- *      used to identify the objects in the array. The `trackexpr` will most 
likely refer to the
- *     `value` variable (e.g. `value.propertyName`). With this the selection 
is preserved
- *      even when the options are recreated (e.g. reloaded from the server).
