2// Implementation of AliPerformanceTPC class. It keeps information from
3// comparison of reconstructed and MC particle tracks. In addtion,
4// it keeps selection cuts used during comparison. The comparison
5// information is stored in the ROOT histograms. Analysis of these
6// histograms can be done by using Analyse() class function. The result of
7// the analysis (histograms/graphs) are stored in the folder which is
8// a data member of AliPerformanceTPC.
