 This service makes the trigger names available.  They are provided
 in the same order that the pass/fail status of these triggers is
 recorded in the TriggerResults object.  These trigger names are
 the names of the paths that appear in the configuration (excluding
 end paths).  The order is the same as in the configuration.

 There are also accessors for the end path names.  

 There are other accessors for other trigger related information from the
 job configuration: the process name, whether a report on trigger results
 was requested and the parameter set containing the list of trigger paths.

 Almost all the functions return information related to the current
 process only.  The second and third getTrigPaths functions are exceptions.
 They will return the trigger path names from previous processes.

 Unit tests for parts of this class are in FWCore/Integration/run_SelectEvents.sh
 and the code it invokes.
