// User switches for CastorPedestalAnalysis to set in cfg are:
//   nevtsample - number of events per sample in which data will be divided
//                for stability checks (default: 0 = do not use),
//   hiSaveflag - flag to save histos of charge per cap-id (default: 0),
//   pedValflag - pedestal validation flag:
//                0 - write out current raw constants (default)
//                1 - write out validated constants
