//-------------------------------------------------------------------------
//                          High Level Trigger ITS tracker
//     reads AliITSclusterV2 clusters and HLT tracks as input and creates 
//       AliITStrackV2 tracks which then can be stored to the HLT ESD.
//     The class inheritates all the main features of the off-line
//       AliITStrackerV2 with some changes in order to load the HLT tracks
//       instead of the off-line TPC tracks. For time performance reasons
//       the tracker is supposed to perform only one reconstruction pass
//       and eventually propagate the tracks back to TPC inner border.
//       For detals how to use it, see RunHLTITS.C macro.
//
