// Description:
//      Beta analysis to analys the Knunu truth from the 
//      generator. This module makes a lot of plots that
//      can be used to study the performance of the event
//      event generators.
//
//
// Environment:
//	Software developed for the BaBar Detector at the SLAC B-Factory.
