The HGTD_IterativeExtensionTool uses an iterative Kalman filter approach to find hits (HGTD_Cluster) in HGTD that are compatible with a track extrapolated to the surfaces of HGTD. During this process, the track itself is not altered, the found hits are returned as an array of HGTD_ClusterOnTrack objects.

TODO:

• exchange chi2/ndof with TMath::Prob?
• add chi2 for the time -> get an estimate at layer 0 (TOF +- beamspot), decorate the TrackParameters with time and timeres before!
