Uses a pushbutton to turn on and off mouse control, and
a second pushbutton to click the left mouse button

Hardware:
* 2-axis joystick connected to pins A0 and A1
* pushbuttons connected to pin D2 and D3

The mouse movement is always relative. This sketch reads
two analog inputs that range from 0 to 1023 (or less on either end)
and translates them into ranges of -6 to 6.
The sketch assumes that the joystick resting values are around the
middle of the range, but that they vary within a threshold.

WARNING: When you use the Mouse.move() command, the Arduino takes
over your mouse! Make sure you have control before you use the command.
This sketch includes a pushbutton to toggle the mouse control state, so
you can turn on and off mouse control.
