    * mfileio/MReadTree.cc:
      - fixed handling of -1 entries in AddFile: root 3.10/02 crashed
+
+   * manalysis/MExtractSignal.[h,cc]:
+     - moved code to extract the signal from Process to
+       new member function FindSignal, I left the arrival time 
+       extraction as commented-out code in the code just as a 
+       demonstration to do this very fast.
