/*************************************************************************
*
* PTimer

* Author: Stefan Pochmann
* Date: Nov 18, 2009
* Version: 1.0
*
* The "P" of "PTimer" is in a quantum superposition - until I decide,
* it stands for both "Pochmann" and "Puzzle".
*
* It's a simple timer very similar to the Speedstacks Stackmat. Keys
* 'x' and '/' (or Alt and CTRL) play the role of the stackmat sensors.
*

* Forum thread: [url]http://www.speedsolving.com/forum/showthread.php?t=16952[/url]
*
* I hope the code is self-explanatory cause I don't feel like explaining it.
