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.

6/**
7 * Provides singleton functionality in a modular sort of way. Make this the
8 * base class of any other class and you immediately gain singleton
9 * functionality. Be sure to make your constructor and various functions use
10 * intellegent scoping. Cleanup and instantiation are performed automatically
11 * for you at first use and program exit. There are two things that you must
12 * do when using this template, first is to inherit from it with the name of
13 * your class filling in for T and then make this class a friend of your class.
14 *@code
15 * // Making the Single Singleton:
16 * class Single : public Singleton<Single>
17 * {
18 * friend class Singleton<Single>;
19 * protected:
20 * Single();
21 * ...
22 * };
23 @endcode
24 * You can still add public functions and variables to your new Singleton child
25 * class, but your constructor should be protected (hence the need for the
26 * friend decleration).
