Subclasses and classes are basically the same thing, except that
subclasses are an 'easy' way to modify the regular class of an object.

Subclasses are limited to 7, 0 (the regular class), 1-7 subclasses.

Subclasses (just like regular classes) have no intrinsic ordering, their
order is given by the lock hierarchy.

Anything else you want to know?
