+   * mmontecarlo/MMcTriggerRateCalc.h,cc:
+     - Now the dimension of fTrigger is set dinamically, to allow
+       the processing of files with an arbitrarily large number of 
+       trigger conditions inside.
+   * macros/trigrate.C:
+     - Adapted the macro to changes above, and added a third argument:
+       the name of a file containing pure NSB events from which the
+       accidental trigger rate is calculated. Previously, this had to 
+       be introduced in the macro by hand by the user.

+!   Modified 4/7/2002, Abelardo Moralejo:
+!   Added one optional input parameter: a camera .root file containing
+!   pure NSB events. One such file is generated running the camera over an
+!   "empty" reflector file, with the NSB option on, and MINPHOT=0. The nsb
+!   files must contain the same trigger conditions as the proton file.
+!   If no nsb file is supplied, the macro will assume no triggers from 
+!   pure NSB fluctuations.
