new interfaces: PlayerService, SetUpService.
new classes: PlayerServer, SetUpServer, PlayerClient, SetUpClient.
Code from "QuizServer" and "QuizService" will be chopped out and
portioned out to these new interfaces and classes.
added QuizLauncher which binds two servers: playerServer and quizServer
to the same registry.
made client look up 'playerServer'. Added 3 new printlns and calls to
three new methods in playerService: getGameList(),
getPlayerView(String), updateView(String).
Added 4 new methods called from PlayerClient getGameList(),
getPlayerView(String), isGameOver(), updateView(String). 
(Mistakenly forgot to mention isGameOver() in last git commit to
PlayerClient).
Added 4 new method called from PlayerClient getGameList(),
getPlayerView(String), isGameOver(), updateView(String). Implementation
code not written yet.
Starting to refactor QuizServer to carve it up into QuizController,
QuizModel, and the two views: PlayerServer and SetUpServer. First step
to rename QuizServer as QuizController.
renamed the interface QuizService to QuizController (following on from
renaming QuizServer to QuizControllerImpl). Also added Eclipsed-prompted
serialVersionUIDs for both. QuizController extends Serializable.
QuizControllerImpl implements Serializable.
a bit of carnage at the moment as I ruthlessly carve up QuizServer
(which was renamed to QuizControllerImpl) and QuizService (renamed
QuizController). Everything except playQuiz() and startGame() was cut
and pasted from QuizControllerImpl to QuizModelImpl. Everything except
playQuiz() was cut and pasted from QuizController to QuizModel.
QuizControllerImpl FKA QuizServer will probably not needed to be
directly bound to the registry as it will be updating server-side views
(called PlayerServer and SetUpServer) and won't have any methods that
the client would need to call directly (via a server stub).
