//
//  Class for handling of ESD track cuts.
//
//  The class manages a number of track quality cuts, a
//  track-to-vertex cut and a number of kinematic cuts. Two methods
//  can be used to figure out if an ESD track survives the cuts:
//  AcceptTrack which takes a single AliESDtrack as argument and
//  returns kTRUE/kFALSE or GetAcceptedTracks which takes an AliESDEvent
//  object and returns an TObjArray (of AliESDtracks) with the tracks
//  in the ESD that survived the cuts.
//
//
//  TODO:
//  - add functionality to save and load cuts
//  - add histograms for kinematic cut variables?
//  - upper and lower cuts for all (non-boolean) cuts
//  - update print method
//  - put comments to each variable
