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).
