-/**

- * A graphical Pong bat. 

- * Displayed as a filled horizontal rectangle that has 

- * a screen location, a width and a height.

- * Has methods for drawing, erasing, moving left and right, 

- * and changing its width (to make the hitting action more challenging).

- * This class should have been called "paddle", following the 

- * standard Pong terminology. But, unaware of this terminology,

- * we called it "bat", and then decided to stick to it.
