// Description:
//      Implementation of resCalc
//      Uses existing GFTracks as reference and calculates
//      residua in XY for TpcClusters.
//      Developped for Test Bench tracking systems using the
//      RK track representation
//
// Environment:
//      Software developed for the PANDA Detector at FAIR.
//
// Author List:
//      Felix Boehmer                     (original author)
//      Maxence Vandenbroucke             (Application of TpcCdcFit2DResCalc to GFTracks)
