Create an application that provides a solution for problem 23.11 by modifying the solution implemented from the BouncingBall.doc file (attached).  The modifications are as follows for the new solution.

• Remove the "Runnable" interface from "BouncingBallPanel" class. 
• Add the "Runnable" interface to "Ball" class
• Modify the "mouseClicked" method in the "BouncingBallPanel"class  to start the thread after each ball is created.  The "Ball" class must receive a reference to the "Bouncing BallPanel" (i.e., to call the "repaint" method)
• Remove the "run" method from the "BouncingBallpanel" note.  The "run" method must be implemented in the "Ball" class.  The inner loop of the "run" method must be removed and the single "move" method call should remain.  Also modify the method so that the delay for each ball is different (i.e., a way to simulate ball moving at different rates)
