/** CbmStsHitProducerIdeal.h
 *@author V.Friese <v.friese@gsi.de>
 **
 ** The ideal hit producer produces hits of type CbmStsMapsHit by copying
 ** the MCPoint position. The position error is set to 1 mum, much 
 ** smaller than can be obtained by any detector. Using the hits from 
 ** this HitProducer is thus equivalent to using MC information
 ** directly, but with the correct data interface.
