      - set version number by one higher because of new data member 
        "fNameSignalCam"

+   * msignal/MExtractTime.[h,cc]
+     - introduce possibility to choose name of MArrivalTimeCam. Need
+       access to different MArrivalTimeCams for comparative extractor
+       studies. Analogues to MPedestalCam in MPedCalcFromLoGain. Default 
+       is "MArrivalTimeCam", like before.
