// LArG4::EC::PresamplerCalibrationCalculator
// Prepared 17-Aug-2004 Bill Seligman
 
// This class calculates the values needed for calibration hits in the
// simulation.
 
// A "calculator" is used in much the same way as a hand-held
// calculator might be.  The user supplies a value and hits 'Enter'
// (i.e., invokes the Process() method).  Then they read off whatever
// values are of interest.
