+     mpedestal/MPedestalSubtract.cc,
+     mpedestal/MPedestalSubtractedEvt.[h,cc]:
+     - changed USample_t finally from Byte_t to UShort_t
+     - adapted Memcpy accordingly
+
+   * mraw/MRawEvtData.[h,cc]:
+     - increased class version to 7
+     - added fNumBytesPerSample for simplification
+     - take fNumBytesPerSample into account
+     - changed draw and print option accordingly
+     - changed reading of pixel information (in fact it is a 
+       simplification allowed by the flexible storage format)
+     - added a private GetSample  member function to be used in
+       data access for drawing a pixel
+     - added returning of the scale (2^((numbytes-1)*8))
+     - FIXME: GetPixelContent must be reimplemented!
+
+   * mraw/MRawEvtPixelIter.[h,cc]:
+     - changed according to changes in MRawEvtData to support 
+       flexible daza format
+     - removed a lot of old, obsolete and unsused member functions
