/**

 1	Experiment with replacing the two-paramter add methods with
 	the one-parameter add method.  What happens and why?

 2	Fix the commented-out line with mousePanel.addMouseMotionListener( ?? )
 	so that the motion of the mouse in the mousPanel can be monitored.

 3	Add code so that the timestamp appears in the output text for each event
