 * GuessController.java

 *  GuessController provides interactive functionality for the GuessFrame GUI.  
 *  Listeners for the GUI elements (ButtonListener , TileListener)are implemented as inner classes.
 *  The  TimerListener class is used to hide the tiles 800 ms after the user has triggered a timer by guessing 
 *  tiles that don't match.
