Lots of cool new stuff, the Server class actually works for everything except

actually interacting with clients, and the Client class is almost there, except
that it doesn't really do anything yet.

+         * base class of any other class and you immediately gain singleton
+         * functionality.  Be sure to make your constructor and various functions use
+         * intellegent scoping.  Cleanup and instantiation are performed automatically
+         * for you at first use and program exit.  There are two things that you must
+         * do when using this template, first is to inherit from it with the name of
+         * your class filling in for T and then make this class a friend of your class.
