+//Software Exercise:
+//1. Update the software system by creating a new library, which includes 
+//   a class that defines the behavior of a bouncing ball on the LCD screen.
+//2. Demonstrate the system with two or more bouncing balls on the screen.
+//3. Show that the system resets the ball locations when you hold the 
+//   accelerometer upside down.
