Message:

 Changes in MFadc. Added possibility to set a shift (for the moment an
 integer number of FADC slices) between the signal peak in the high gain
 and in the low gain.

+// 
+// Added switch to low gain (see MFadc.cxx). Before, in all events all 
+// pixels had low gain branch, no matter how small the signal in the high
+// gain was. Now we require a minimum signal in the high gain to fill the
+// low gain slices with the scaled-down signal. In case the switch does
+// not occur, the low gain slices are simply the continuation of the
+// high gain ones, with the noise the same as in the high gain.
