The Bouncy Ball Assignment

Your mission is to write a client and a server using RMI.

The client should show three balls. The balls should move due to user input. I implement the following rules, though you can chose other rules if you like.

Ball #1 starts selected.
If the user clicks on a ball, the ball is 'selected'.
Otherwise, move the selected ball to the clicked-on spot.

One might also use these rules ...

Ball #1 starts selected.
When the user clicks, the selected ball moves to that spot.
When the user types a '1', a '2' or a '3', that ball becomes selected.

When a client moves a ball, the client also tells the server.

When the server is told a ball has moved, it tells all the clients.
