/** CbmPVFinderIdeal
 *@author V.Friese <v.friese@gsi.de>
 **
 ** Ideal primary vertex finder. It takes the start vertex of primary
 ** MCTracks.
 ** Warning: This works only if the MC input tracks really start from
 ** the primary vertex and are not displaced by hand.
 ** The primary vertex should ideally be taken from the appropriate
 ** MC class, which is not yet implemented.
