  // tracks are based on the TPC tracks, and only updated from the ITS information

  // 1) extract MC information for TPC and ITS from specific data blocks and store in
  //    intermediate vector arrays
  // 2) extract TPC tracks, update with MC labels if available, the track parameters
  //    are estimated at the first cluster position
  // 2.1) propagate to last cluster position and update kTPCout, sets also outer param (fOp)
  // 2.2) update kTPCin, sets also inner param (fIp) and TPC inner param (fTPCInner)
  // 2.3) update kTPCrefit using the same parameters at the first cluster position
  //      HLT has strictly spoking no refit, but we want the flag to be set
  //      can be changed to be done after all the individual barrel detector parameters
  //      have been updated by looping over the tracks again
  // 3) extract ITS tracks, the tracks are actually TPC tracks updated from the ITS
  //    tracking information
  // 3.1) TODO 2010-07-12: handle ITS standalone tracks by updating kITSout before kITSin
  // 3.2) update with kITSin
  //    TODO 2010-07-12 find out if the kITSrefit has to be set as well
  // 4) extract TRD tracks and add to ESD
  //    TODO 2010-07-12 at the moment there is no matching or merging of TPC and TRD tracks
  // 5) Add Trigger Detectors 
  //    VZERO, ZDC
