   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.
