+   * msim/MHPhotonEvent.cc:
+     - automatic binning for case 3
+     - new case 5
+
+   * msim/MHPhotonEvent.h:
+     - this can be a huge memory consumption and we don't need double
+       precision (range) accordingly changed all TH*D to TH*F.
+       consequently increased class version number
