//
//  This class is  a simple preprocessor for VZERO detector.
//
//  It gets High Voltage values for a given run from DCS and Pedestal values from DAQ 
//  and writes them as Calibration MetaData into OCDB/VZERO/Calib/Data
//  It also retrieves FEE parameters from DCS archive   
//  and writes them as Trigger MetaData into OCDB/VZERO/Trigger/Data 
//  (to be used for trigger simulation)
