// AliTOFTrackV2 class
//
// Author: F. Pierella | pierella@bo.infn.it
//
// Description: output of AliTOFReconstructionerV2
// TRD tracking capabilities have been foreseen by including the member
// variables fxTRD, fyTRD, fzTRD and momentum components fPxTRD, fPyTRD, fPzTRD.
// 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 and time of flight itself
