2// Class for handling of ESD track cuts.
3//
4// The class manages a number of track quality cuts, a
5// track-to-vertex cut and a number of kinematic cuts. Two methods
6// can be used to figure out if an ESD track survives the cuts:
7// AcceptTrack which takes a single AliESDtrack as argument and
524916f0 8// returns kTRUE/kFALSE or GetAcceptedTracks which takes an AliESDEvent
73318471 9// object and returns an TObjArray (of AliESDtracks) with the tracks
10// in the ESD that survived the cuts.
11//
12//
524916f0 13// TODO:
73318471 14// - add functionality to save and load cuts
73318471 15// - add histograms for kinematic cut variables?
16// - upper and lower cuts for all (non-boolean) cuts
17// - update print method
73318471 18// - put comments to each variable
