 * AUTHOR:             Ian Morris
 *
 * DESCRIPTION:
 * Performs the function of the bulb in a light bulb switching system. Runs
 * on the controller board of the evaluation kit and forms the PAN coordinator
 * of the system. Once at least once light switch has joined the network the
 * then coordinator waits for a data frame to arrive. Upon reception the state
 * of the bulb (four LEDs on the controller board) is toggled.
