 Function called by ATLFast::Finish at the end of the job

.............................................
  This function searches for tracks, by scanning through
  the list of MC particles. If a track is found, its momentum is
  smeared using function RESMUO.
  Three options for track-momentum smearing are  available:
       stand-alone Track System
       Inner Detector alone
       combined
  The parametrization for the momentum smearing is coded  in RESMUO.
  Isolated and non-isolated tracks are stored in The TClonesArray of tracks
  and the energy clusters associated with them are removed.
  Tracks outside the ETA-coverage or below the p_T-threshold are lost.
.............................................

  Returns helix parameters in polar coordinates from the original position
  and momentum at the vertex of the track.
  Input Arguments:
  ================

   charge = particle charge
   vert   = vertex coordinates
   pvert  = quadrimpulse of the particle

  Output Arguments:
  =================

    b[0] Impact parameter              ! output is ATLAS standards
    b[1] Z of perigee                  ! in cm
    b[2] phi of helix (-pi<phi<pi)     ! in rad
    b[3] cot(theta)
    b[4] (1/pt)*charge                 ! in 1/GeV
