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