-// The class AliCFTrackIsPrimaryCut is designed to select reconstructed tracks
-// with a small impact parameter and tracks which are (not) daughters of kink
-// decays and to provide corresponding QA histograms.
-// This class inherits from the Analysis' Framework abstract base class
-// AliAnalysisCuts and is a part of the Correction Framework.
-// This class acts on single, reconstructed tracks, it is applicable on
-// ESD and AOD data.
-// It mainly consists of a IsSelected function that returns a boolean.
-// This function checks whether the considered track passes a set of cuts:
-// - min. and max. distance to main vertex in transverse plane (xy)
-// - min. and max. longitudinal distance to main vertex (z)
-// - min. and max. distance to main vertex as ellpise in xy - z plane
-// - all above cuts on absolute values or in units of sigma (resolution)
-// - min. and max. distance to main vertex in units of sigma (resolution)
-// - max. transverse (xy) and longitudinal (z) impact parameter resolution
-// - require that the dca calculation doesn't fail
-// - accept or not accept daughter tracks of kink decays
-//
-// By default, the distance to 'vertex calculated from tracks' is used.
-// Optionally the SPD (tracklet based) or TPC (TPC only tracks based) vertex
-// can be used.
-// Note: the distance to the TPC-vertex is already stored in the ESD,
-// the distance to the SPD-vertex has to be re-calculated by propagating each
-// track while executing this cut.
-//
-// The cut values for these cuts are set with the corresponding set functions.
-// All cut classes provided by the correction framework are supposed to be
-// added in the Analysis Framwork's class AliAnalysisFilter and applied by
-// the filter via a loop.
