  A class for creating a schedule based on paths in the configuration file.
  The schedule is maintained as a sequence of paths.
  After construction, events can be fed to the object and passed through
  all the modules in the schedule.  All accounting about processing
  of events by modules and paths is contained here or in object held
  by containment.
 
  The trigger results producer and product are generated and managed here.
  This class also manages endpaths and calls to endjob and beginjob.
  Endpaths are just treated as a simple list of modules that need to
  do processing of the event and do not participate in trigger path
  activities.
 
  This class requires the high-level process pset.  It uses @process_name.
  If the high-level pset contains an "options" pset, then the
  following optional parameter can be present:
  bool wantSummary = true/false   # default false
 
  wantSummary indicates whether or not the pass/fail/error stats
  for modules and paths should be printed at the end-of-job.
 
  A TriggerResults object will always be inserted into the event
  for any schedule.  The producer of the TriggerResults EDProduct
  is always the first module in the endpath.  The TriggerResultInserter
  is given a fixed label of "TriggerResults".
 
  Processing of an event happens by pushing the event through the Paths.
  The scheduler performs the reset() on each of the workers independent
  of the Path objects.
 
  ------------------------
 
  About Paths:
  Paths fit into two categories:
  1) trigger paths that contribute directly to saved trigger bits
  2) end paths
  The Schedule holds these paths in two data structures:
  1) main path list
  2) end path list
 
  Trigger path processing always precedes endpath processing.
  The order of the paths from the input configuration is
  preserved in the main paths list.
 
  ------------------------
 
  The Schedule uses the TriggerNamesService to get the names of the
  trigger paths and end paths. When a TriggerResults object is created
  the results are stored in the same order as the trigger names from
  TriggerNamesService.
