Re: about "set" variables

In a setter method, as you show, the intent is to take the argument
and use it to change the state of the heatbug.  So, "i" and "o" are
values passed-in to set the state of the heatbug, i.e. the instance variables
"idealTemperature" and "outputHeat". 

In some cases, you might have a setter method that took one argument
and set several things based on that argument.  In other cases, you
might have several arguments, which you would validate somehow, and
use it to set just one instance variable.

In a header (.h file), these names have no functional
significance; they are just names that can be used to suggest the use
of the argument.

In the implementation (.m file), the argument to a method needs to
have a different name from instance variables.
