// File: CCalHit.h
// Description: Hit class for Calorimeters (Ecal, Hcal, ...)
//
// One Hit object should be created
// -for each new particle entering the calorimeter
// -for each detector unit (= cristal or fiber or scintillator layer)
// -for each nanosecond of the shower development
//
// This implies that all hit objects created for a given shower
// have the same value for
// - Entry (= local coordinates of the entrance point of the particle
//            in the unit where the shower starts) 
// - the TrackID (= Identification number of the incident particle)
// - the IncidentEnergy (= energy of that particle)
