New task to study fake tracks in simulation: need to access the recoParam used during the reconstruction; associate reco & MC tracks either by using MC labels or by comparing the position of the clusters (default); fill counters to get the detailed statistics of good tracks, fakes, events containing fakes, ... ; fill histograms to compare the chi2, number of associated clusters, pt, DCA, ... of good tracks and fakes (Philippe P.)
