I use categories to separate out additional methods beyond the basic 
accessors and init / constructor / dealloc.

In this case, though, since there are different subclasses, a 
separate strategies class seemed to work better. Thanks for the 
suggestion, though, as it gives me an idea for reverse sorting with 
arrays.
