+/*
+ Class to process/filter reconstruction information from ESD, ESD friends, MC and provide them for later reprocessing
+ Filtering schema - low pt part is downscaled - to have flat pt specatra of selected topologies (tracks and V0s)
+ Downscaling schema is controlled by downscaling factors
+ Usage:
+ 1.) Filtering on Lego train
+ 2.) expert QA for tracking (resolution efficnecy)
+ 3.) pt reoslution studies using V0s
+ 4.) dEdx calibration using V0s
+ 5.) pt resolution and dEdx studies using cosmic
+ +
+ 6.) Info used for later raw data OFFLINE triggering (highPt, V0, laser, cosmic, high dEdx)
+
+ Exported trees (with full objects and dereived variables):
+ 1.) "highPt" - filtered trees with esd tracks, derived variables(propagated tracks), optional MC info +optional space points
+ 2.) "V0s" - - filtered trees with selected V0s (rough KF chi2 cut), KF particle and corresponding esd tracks + optionla space points
+ 3.) "Laser" - dump laser tracks with space points if exests
+ 4.) "CosmicTree" - cosmic track candidate (random or triggered) + esdTracks(up/down)+ optional points
+ 5.) "dEdx" - tree with high dEdx tpc tracks

+ -Chi2 distance to the closest tracks at reference radius of TPCin
+ -Overlap factors - fraction of shared clusters or missing region
+ -Chi2 distance at DCA
+ Information matrix:
+ -matrix closest tracks from each categories
+ -characterization - chi2, index,chi2, overlap ratio
+
+ Decissions:
+ 0.) Kink decay or catastophic multiple scaterring
+ (combining all track categories)
+ - small chi2 at the DCA
+ - significantly large deflection angle
+ - Combinatorial algorithm - to decrease CPU time restriction of investigation to tracks with small DCA at refernce radius
+
+ 1.) if (TPConly && !(TPC+ITS) && ITSonly match ) {
+ if (!kink) TPCOnly.addoptITS
+ if (kink) TPConly sign
+ }
+
+ 2.) Overlap tracks - Refit with doUnfold
