Time_Timer.py

'''
A simple Time Timer app made of ShapeNodes.
<Change Line 120 for seconds or minutes counting>
<Uncomment Line 126 and fill in your shortcut name to 
automatically run other shortcut you defined
after timer stopped>
Odd touch attemps will start the timer 
Even touch attemps will stop the timer
Stops automatically when the set times passed
