Wrapper around a member function pointer. The class instance whose member function to call is passed as a reference to the operator().

1) Wraps a non-const member function with no parameters.
2) Wraps a const member function with no parameters.
3) Wraps a non-const member function with a single parameter.
4) Wraps a const member function with a single parameter.
