 *
 * Revision 1.1.1.1  2002/06/05 21:56:32  root
 * CS101 comes to Olin finally.
 *
 * Revision 1.10  1999/11/01 01:52:15  mharder
 * Fixed NullPointerException in constructor
 *
 * Revision 1.9  1999/08/16 16:56:47  jsmthng
 * Updated to make JavaDoc happy.
 *
 * Revision 1.8  1999/07/27 18:55:50  las
 * Patched up DefaultFrame (mostly docs) and DefaultGameFrame (aesthetics
 * and docs).
 *
 * Capitalized the name of the GameControllable interface.
 *
 * Moved the other four interfaces (Pausable, Resetable, Startable,
 * Stoppable) to cs101.util as they really have nothing to do w/awt or
 * windowing in particular.
 *
 * Also, added unpause() to Pausable as it doesn't make much sense to be
 * able to pause but not unpause something.
 *
 * Revision 1.7  1999/07/13 20:42:47  pnjoroge
 * This is a new implementation of DefaultGameFrame. The frame has
 * four functionalities that have to be implemented by the user . This
 * include start, stop, resetand pause.
