Third normal form for classes

John Cowan - Third normal form for classes:

"If the state can be partitioned into two non-overlapping sub-states such that no methods depend on both of them, then the class should be refactored into two classes with separate states. This also improves encapsulation, as the methods in one class can now be changed without regard to the internals of the other class."
