// LArG4::EMECSupport::CalibrationCalculator
// Prepared 9-Sep-2004 Mikhail Leltchouk
 
// This class calculates the values needed for calibration hits in the
// simulation. 
 
// This particular class is meant to be be used for particular volumes
// in the endcap.  Some volumes have identifiers that change
// significantly (mixed samplings, types, subdets) within that single
// volume.  This calculator handles those special cases.
