// Implementation of the AliPerformanceTask class. It checks reconstruction performance \r
// for the reconstructed vs MC particle tracks under several conditions. For real data \r
// the control QA histograms are filled.\r
//\r
// The comparison output objects deriving from AliPerformanceObject \r
// (e.g. AliPerformanceRes, AliPerformanceEff, AliPerformanceDEdx, AliPerformanceDCA ...) \r
// are stored in the output file (details in description of these classes).\r
