/**
 * The game config class encapsulates the configuration information for a
 * particular type of game. The hierarchy of game config objects mimics
 * the hierarchy of game managers and controllers. Both the game manager
 * and game controller are provided with the game config object when the
 * game is created.
 *
 * <p> The game config object is also the mechanism used to instantiate
 * the appropriate game manager and controller. Every game must have an
 * associated game config derived class that overrides {@link
 * #getControllerClass} and {@link #getManagerClassName}, returning the
 * appropriate game controller and manager class for that game. Thus the
 * entire chain of events that causes a particular game to be created is
 * the construction of the appropriate game config instance which is
 * provided to the server as part of an invitation or via some other
 * matchmaking mechanism.
