   //   Implements rejection of events incompatible with the (principal) on-line DAQ trigger for each run of E789.
   //
   //   Used for analysis of events when KVEventSelector::SetTriggerConditionsForRun() is called in KVEventSelector::InitRun().
   //
   //   This will do 2 things: for physics runs (where the principal trigger for FAZIA was "Mult2"), we retain only
   //   events for which the trigger bit pattern is compatible with "Mult2", which can be either "Mult2" alone or
   //   "Mult2"+"Mult1/100" (see KVFAZIA::SetTriggerPatternsForDataSet() and KVFAZIA::GetTriggerForCurrentRun()).
   //   Events for which only "Mult1/100" (multiplicity 1 trigger downscaled by 100) fired are rejected.
   //
   //   The 2nd thing this will do is reject the (very small) number of events where FAZIA is not present, only INDRA
   //   (in this case there is no FAZIA trigger bit pattern, which is not consistent with a trigger pattern "Mult2").
   //
   //   When analysing filtered simulated data, this just rejects all events for which the number of particles
   //   hitting FAZIA (identified/calibrated or not) is less than 2.
