   This is a trivial event processor.  All it does it
   set rEvent[0] to 1.  That allows a strip chart spectrum
   of event rate vs. time to be created by making rEvent[0] the y
   axis of the strip chart and a timestamp the x axis.

   We also compute the calibrated time as a tree parameter.
   named cTime  which will be the time in milliseconds.
