19// Manager class for TOF reconstruction.
20//
21//
22//-- Authors: Bologna-ITEP-Salerno Group
23//
24// Description: Manager class for TOF reconstruction (derived from TTask)
25// Summary of the main methods:
26// - extraction of the TPC (assumed to be) reconstructed tracks
27// comment: it has to me moved as soon as possible into a separate
28// class AliTOFTrackReader (K. Safarik suggestion)
29// - geometrical propagation of the above tracks till TOF detector
30// - matching of the tracks with the TOF signals
31//
32// Remark: the GEANT3.21 geometry is used during the geometrical propagation
33// of the tracks in order to know the current volume reached by the track.
34//
