class AliPerformanceMatch: public AliPerformanceObject

 Implementation of AliPerformanceMatch class. It checks the track matching
 quality (residuals, pulls) bewteen tracking detectors TPC-ITS and TPC-TRD
 with TPC as the reference detector. In addition, the ITS and TRD track
 reconstruction efficiency with respect to TPC is calculated.

 The matchinig quality parameters are stored in the THnSparse histograms.
 The analysis of these histograms to extract reference information is done in
 the Analyse() function (post-processing).

 The histograms with reference information can be exported to the ROOT folder.
