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