Changes:
- creator (static) methods, and singleton methods (static) are always at the top of the class
- Constructors, destructros, and init methods comes next
- Then the instance methods for the class
- Then the overriden methods
- and finally the ivars
Also, overriden methos have the "override" context keyword
... instead of sharedXXX / purgeXXX.
They are more C++ friendly, and also easier to remember.
common files + Mac files + iOS files + tests/samples files were updated.
The old methods are deprecated now.
