/** CbmMvdStripsMatchTracks.h
 *@author V.Friese <v.friese@gsi.de>
 **
 ** Task class for matching a reconstructed CbmMvdStripsTrack with a simulated
 ** CbmMCTrack. The matching criterion is a maximal number of common
 ** hits/points. The task fills the data class CbmMvdStripsTrackMatch for
 ** each CbmMvdStripsTrack.
