* This sketch uses the Macetech Chronodot and I2C protocol
* to program a cleanup countdown clock for the p comp room.
*
* Code for the I2C communication with the Chronodot was
* adapted from code written by Maurice Ribble. Documentation
* of it can be found here: http://www.glacialwanderer.com/hobbyrobotics/?p=12
