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.
