1. CPSet and CPMutableSet are now abstract super classes that create appropriate concrete subclasses behind the scenes. 2. CPSet subclassers need only implement -count, -member:, and -objectEnumerator. 3. CPMutableSet subclassers need only implement -count, -member:, -objectEnumerator:, -addObject:, and removeObject:. 4. Added more CPSet tests. 5. Added _CPKeyValueCodingSet which subclasses CPSet for set returns in valueForKey:. Reviewed by me.
