17// Manager class for TOF reconstruction.
18//
19//
20//-- Authors: Bologna-ITEP-Salerno Group
21//
22// Description: Manager class for TOF reconstruction (derived from TTask)
23// Summary of the main methods:
24// - extraction of the TPC (assumed to be) reconstructed tracks
25// comment: it has to me moved as soon as possible into a separate
26// class AliTOFTrackReader (K. Safarik suggestion)
27// - geometrical propagation of the above tracks till TOF detector
28// - matching of the tracks with the TOF signals
29//
30// Remark: the GEANT3.21 geometry is used during the geometrical propagation
31// of the tracks in order to know the current volume reached by the track.
32//
