/*------------------------------------------------------------------------Monitor.h
*
* The pourpose of the monitor is to interpret and dispatch data The idea is to
* try to set up a relatively flexible interpreter for data coming in from the
* serial port and also commands coming from the usb port. Using a jump table which
* is populated by other modules who register the action to be taken.
*
* ------------------------------------------- current vocabulary.
* Deal with multi line data.
* SOD[ :]Start of multiline data
* EOD[ :]End of multiline data
* SYN[? ]Say Hello
* SWV[? ]Software version
*
* all remaining items are sent to the monitored device
