 // This object runs on a thread and knows how to interpret messages sent by the
 // talk mediator. The mediator posts messages to a queue which the thread polls
 // (in a super class).
 //
 // Example usage:
 //
 //   MediatorThread m = new MediatorThreadImpl(pass in stuff);
 //   m.start(); // Start the thread
 //   // Once the thread is started, you can do server stuff.
 //   m.Login(loginInformation);
 //   // Events happen, the mediator finds out through its pump more messages
 //   // are dispatched to the thread eventually we want to log out.
 //   m.Logout();
 //   delete m; // Also stops the thread.
