//  This class is used by G4SDManager for book keeping the
// sensitive detector modules and hits collections. The order of
// hits collections stored in G4HCofThisEvent is same as the
// order of HClist. 
//  The order may vary from run to run, if the user adds/changes
// some of his/her sensitive detector modules.
//  In case user wants to make G4Run object persistent, this
// G4HCtable class object should be copied and stored with
// G4Run object.
