/**
 * A noisy golfball for RoboCup Soccer.
 * <B>Introduction</B><BR>
 * GolfBallNoiseSim implements a golf ball for RoboCup
 * soccer simulations.  The ball is also the scorekeeper and 
 * the referee; after all who would know better whether a 
 * scoring event occured?
 * <P>
 * A "shot clock" keeps track of how long since a scoring
 * event occured.  If it times-out, the ball is reset to the
 * center of the field.
