 * Self_Regulate -- Regulates the logic timer to result in smooth animation                    *
 *                                                                                             *
 *    The self regulation process checks the number of frames displayed                        *
 *    per second and from this determines the amount of time to devote                         *
 *    to internal logic processing. By adjusting the time allotted to                          *
 *    internal processing, smooth animation can be maintained.                                 *
