+  ButtonMouseControl
+ 
+ Controls the mouse from five pushbuttons on an Arduino Leonardo.
+ 
+ Hardware:
+ * 5 pushbuttons attached to D2, D3, D4, D5
+ 
+ 
+ The mouse movement is always relative. This sketch reads 
+ four pushbuttons, and uses them to set the movement of the mouse.
+ 
+ WARNING:  When you use the Mouse.move() command, the Arduino takes
+ over your mouse!  Make sure you have control before you use the mouse commands.
