Made predicate and function types callable in the sense that

Browse Source 
callable(I, T) returns True when I is an object of a type T or
of a subtype of T.  Also implemented a measure to avoid an
infinite loop when user-defined predicate and function classes
do not properly overload the __call__ method (including the
cases of directly instantiating the base classes such as
UnaryPredicate0D and BinaryPredicate1D).
