So, if I want to break down a large class into multiple files with each file 
containing one category, what should I write?
Object subclass: MyClass [
    | var1 var2|
]

MyClass class >> category: 'instance creation' [
    new [...]
]

MyClass category: 'category1' [
    method1 []
]

MyClass category: 'category2' [
    method2 []
]

What does the keyword "extend" do?
