 * File:     receiver.c      
 * Author:   Charles Gruenwald III - [e-mail]
 * Date:     12-14-2003
 *
 * Description: receiver will sit in a tight while loop looking for
 * values received over the radio. Any value it receives it will then
 * show on the leds and send over the serial line using the uart. It is
 * to be used with compatable hardware (nymph/mica2).
