// Description:
//	Class PndEmcDigiCalibrator
//      Do an energy and position corrections for EMC cluster
//      PndEmcDigiCalibrator is a factory which call specific method depending on the input parameter "method"
//      method=1 - PndEmcClusterHistCalibrator is called, which perform correction from the interpolation on 2-dimensional histogram on (Energy, theta)
//      method=2 - PndEmcClusterSimpleCalibrator is called, where energy correction is parametrised as a function of (Energy, theta)
//      PndEmcAbsClusterCalibrator - abstract interface class
//
// Author List:
//      D.Melnychuk
//      PndEmcClusterHistCalibrator class is based on code PndEmcMakeCorr.cxx
//      (A. Biegun, M. Babai)
//      PndEmcClusterSimpleCalibrator class is based on EmcPhotonSimpleCalib class in Babar framework (Jan Zhong)
