/** \class edm::HLTGlobalStatus
 *
 *  
 *  The HLT global status, summarising the status of the individual
 *  HLT triggers, is implemented as a vector of HLTPathStatus objects.
 *
 *  If the user wants map-like indexing of HLT triggers through their
 *  names as key, s/he must use the TriggerNamesService.
