+// 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.
+//
+// Tuple elements are copied by value, and stored in the tuple. See the unit
+// tests for more details of how/when the values are copied.
+//
+// Example usage:
+// // These two methods of creating a Tuple are identical.
+// Tuple2<int, const char*> tuple_a(1, "wee");
+// Tuple2<int, const char*> tuple_b = MakeTuple(1, "wee");
+//
+// void SomeFunc(int a, const char* b) { }
+// DispatchToFunction(&SomeFunc, tuple_a); // SomeFunc(1, "wee")
+// DispatchToFunction(
+// &SomeFunc, MakeTuple(10, "foo")); // SomeFunc(10, "foo")
+//
+// struct { void SomeMeth(int a, int b, int c) { } } foo;
+// DispatchToMethod(&foo, &Foo::SomeMeth, MakeTuple(1, 2, 3));
+// // foo->SomeMeth(1, 2, 3);

+// Tuple0 is supplied to act as a 'void' type. It can be used, for example,
+// when dispatching to a function that accepts no arguments (see the

+// Tuple1<A> is rarely useful. One such use is when A is non-const ref that you
