/**
 * This application stresses the blocking send and receive commands for the c based 
 * API of tosthreads.  Three threads are run, each thread toggling a different 
 * colored LED. If a node has TOS_NODE_ID == 0 it will try and receive in 
 * an infinite loop, toggling one of the three Leds upon reception.  If it has 
 * TOS_NODE_ID == 1, it will try to send in an infinite loop, toggling one of the three
 * Leds upon the completion of a send.  Thread 0 toggles the Led0, Thread 1 toggles 
 * Led1, and Thread 2 toggles Led2.
