0008  Description: The output of this module is used for test purposes.
0009 It is a filter module that makes a filter decision based on a
0010 randomly generated number.  The fraction of events that pass the
0011 filter (in the limit of infinite statistics) is a parameter
0012 that must be set in the configuration file.  The parameter
0013 type and name is "untracked double acceptRate".
