addition it controls a electronic "buddy" that blocks the keyboard to remind the
user to take a break from the computer once in a while.

Example Usage:
	guardian kitty "You can do it!" /dev/ttyUSB0
	guardian trees "You should take a walk" /dev/ttyS0
To raise the "buddy"'s arm again use:
	guardian raise /dev/ttyUSB0
