/* this code is here to test the waveforwe generator and reveal the issues involved in programming track operations.
 *  
 *  It tests the Waveform genartor and demonstrates how a DCC  API function can be simply written  
 *  to transmit and receive DCC data on the programming track.
 *  
 *  Important... DCCWaveform.h contains hardware specific confioguration settings 
 *  that you will need to check.  
 *  
 *  Notes: the waveform generator sends reset packets on progTrack when it has nothing better to do, this means that
 *  the decoder does not step out of service mode. (The main track sends idles).
 *  It also means that the API functions dont have to mess with reset packets.
