//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
// DESCRIPTION
//   This example illustrates the use of basic signal tracing. Action
//   occurs in both main.cpp and here. Notice the use of argv to turn
//   tracing on/off, and the use of map to aid the selection of what
//   to trace. All of the activity/processing is bogus, and simply
//   present to generate some waveform activity.
