// Description:
//      Header for PndLmdHitPair
//      It has fields for exactly two sensor hits (after cluster finder),
//      each hit has one row and col. It also has exactly two TVector3 for
//      hit coordinate in the LMD coordinate system. This info must be
//      supplied by LmdPairFinderTask (or user) and cannot be decoded in
//      this class itsel.
//
// Environment:
//      Software developed for the PANDA Luminosity Detector at FAIR.
//
// Author List:
//      Roman Klasen (roklasen@uni-mainz.de or klasen@kph.uni-mainz.de) by a template from Tobias Stockmanns (IKP - Juelich)
