/** FairTutorialDetHitProducerIdealMissallign.h
 *@author Florian Uhlig <f.uhlig@gsi.de>
 **
 ** The ideal hit producer produces hits of type CbmTutorialDetHit
 ** by copying the MCPoint position. At the same time it will shift
 ** the hit position by a given offset in x- and y-direction. This
 ** shift should mimic a missalignment of the detector due to inaccurate
 ** measurement of the detector positions.
 ** The position error is set to 1 mm.
