Detailed Description

Class to store data from CAEN V1720, 250MHz FADC.

Full info on CAEN V1720 module http://daq-plone.triumf.ca/HR/VME/CAEN/v1720rev9.pdf/view

This class encapsulates the data from a single board (in a single MIDAS bank). This decoder is for the default or ZLE version of the firmware. Not the DPP firmware
