+/* Interfaces to a Sparkfun Blackberry Trackball Breakout Board and uses mbed's
+   USBMouse class to make it look like a mouse to a PC.  Uses the trackball
+   motion to move the mouse pointer, pushing down on the trackball will trigger
+   a microswitch which will act as a left button click, and the LEDs under the
+   trackball will be lit different colours depending on what the user is
+   currently doing with the device (red for no motion, green when the trackball
+   is being moved, and blue during button clicks).  It does use some other
+   utility classes from acceleration.h to provide acceleration to the trackball
+   motion.
