Detailed Description

Produces the central entry point to full PAT trigger information.

This producer extract general trigger and conditions information from

the edm::TriggerResults written by the HLT process,
the ConditionsInEdm products,
the process history and
the GlobalTrigger information in the event and the event setup and writes it together with links to the full PAT trigger information collections and PAT trigger match results to
the pat::TriggerEvent
