//     Class to analyse tracks for calibration                               //
//    to be used as a component in AliTPCSelectorTracks                     //
//     In the constructor you have to specify name and title                 //
//     to get the Object out of a file.                                      //
//     The parameter 'clusterParam', a AliTPCClusterParam object             //
//      (needed for TPC cluster error and shape parameterization)            //
//     Normally you get this object out of the file 'TPCClusterParam.root'   //
//     In the parameter 'cuts' the cuts are specified, that decide           //
//     weather a track will be accepted for calibration or not.              //
//                                                                           //
