* LEDRemote version 1.0 is a program that listens for ACII characters from a 
* websocket.  If the correct ASCII characters are sent, the onboard LED on 
* a Freescale Freedom board (K64F) will light an LED.  For example, if "R1" or 
* "R2" is received the RED LED gets exercised.  "B1" and "B0" exercises the blue 
* LED, and "G1" and "G0" exercises the green LED.
