// AliTOFTrack class
//
// Authors: Bologna-ITEP-Salerno Group
//
// Description: class for TPC data about extracted tracks for TPC-TOF
// matching (cfr. TDR Section 4.4).
// TRD tracking capabilities have been foreseen by including the member
// variables fRxTRD and fRyTRD.
// It is the candidate class to be written in TreeR for each event.
//
// Member variable summary description: 
// - track momentum and position in the last TPC padrow 
// - track length as given by the geometrical propagation
// - reconstructed mass from time of flight
