//
// Component: PhysicsTowerDataMaker.hh
//
// Purpose:   This is the class that makes the PhysicsTowerData object.
//
// Notes:     This maker class uses a data input source and a tower calculator object to make physics towers (see SourceHEPG.hh and
//            SourceCalData.hh for input source examples and StandardCalculator and FourVecCalculator for calculator examples). The
//            default constructor of this class uses SourceCalData and StandardCalculator, i.e. the Run1b default.
//
// Created:   13/09/1999  Pierre Savard
//
// History:
//            30/08/2000  Matthias Toennesmann - Added description string to calling parameters of clump function.
