  This task looks at the output from all other tasks (as stored in their 
  ProblemsCurrentLB histograms), and combines the output into its own ProblemsCurrentLB histogram.  Its own ProblemsCurrentLB histogram, though, is marked with the setLumiFlag, so that its contents will be stored for every lumi section.
