 // A Tuple is a generic templatized container, similar in concept to std::pair.
 // There are classes Tuple0 to Tuple6, cooresponding to the number of elements
 // it contains.  The convenient MakeTuple() function takes 0 to 6 arguments,
 // and will construct and return the appropriate Tuple object.  The functions
 // DispatchToMethod and DispatchToFunction take a function pointer or instance
 // and method pointer, and unpack a tuple into arguments to the call.
