// LArG4::HEC::LocalGeometry
 
// This class contains the geometry calculations needed to calculate
// an identifier for a given G4Step.
 
// 05-Apr-2006: Pavol Strizenec, adaptation from TB LocalCalculator to Atlas
 
// Note: This class is intended for use in calculating identifiers in
// both active and inactive regions of the detector.  For calibration
// studies, it must work properly whether the energy is deposited in
// the liquid argon or the absorber.
