Preliminary Debug Code for Arduino Due based Royal Game of Ur

ArduinoUrDebug

/*********************************************************
  Arduino Due Royal Game of Ur.
  This version is meant to interface with LabView (or other serial device)

  Code Heavily modified to run with Arduino Due, might still be compatible with
  other AVR micros though. Who knows. Too much weirdness going on here. 

  Command List:
  ?IDN: - Identify Device
  !HCF: - Halt & Catch Fire
