/**
 * A game manager that wishes to make use of the turn game services should
 * implement this interface and create a {@link TurnGameManagerDelegate}
 * which will perform the basic turn game processing and call back to the
 * main manager via this interface.
 *
 *  The basic flow of a turn-based game is as follows:
 * 
 * GameManager.gameWillStart()
 * GameManager.gameDidStart()
 *   TurnGameManagerDelegate.setFirstTurnHolder()
 *   TurnGameManagerDelegate.startTurn()
 *     TurnGameManager.turnWillStart()
 *   TurnGameManagerDelegate.endTurn()
 *     TurnGameManager.turnDidEnd()
 *   TurnGameManagerDelegate.setNextTurnHolder()
 *   TurnGameManagerDelegate.startTurn()
 *     ...
 * GameManager.endGame()
