0009   \brief    Produces the central entry point to full PAT trigger information
0010
0011    This producer extract general trigger and conditions information from
0012    - the edm::TriggerResults written by the HLT process,
0013    - the ConditionsInEdm products,
0014    - the process history and
0015    - the GlobalTrigger information in the event and the event setup
0016    and writes it together with links to the full PAT trigger information collections and PAT trigger match results to
0017    - the pat::TriggerEvent
0018
0019    For me information, s.
