the difference between the IsKindOf and IsMemberOf methods (and their cousins
that take class names instead of class objects as args) is how they handle subclasses.
if an object x is an instance of class B (which is a subclass of A) then
x is a kind of A but x is NOT a member of A.
(x is both a kind of B and a member of B)

for more info look in the concepts section on objective C or the
reference for the class Object.
