FRDM-K64F Code Share / Mbed 2 deprecated Websocket_Test

Simple test for commanding the RGB LED. Use your mbed websocket to send a message, composed by a letter and a number. The letter can be 'r', 'g', or 'b', which is the LED color, and the number is 0 or 1, which is the logic state. Remember that the board LEDs light up with a 0 level.
