/** CbmStsMapsHit
 ** Class for MAPS detector hit
 **@author Michael Deveaux <m.deveaux@gsi.de>
 ** Acknowledgements to M. Al-Turany, D. Bertini, G. Gaycken
 ** Version beta 0.1 (02.02.2005)
 ** Slight modifications by V. Friese to match coding conventions
 **
 ** Meaning of RefIndex:  Index of corresponding MCPoint
 **                       -1 if fake or background hit
 **
 ** Meaning of Flag:       0 = Hit ok
 **                       -1 : Hit lost due to detection inefficiency
