  //so passing in the owning EDProducer is a pain for me (S. Harper)
  //and its only needed for legacy/stage1 L1 info which is mostly obsolete now
  //defined a new constructor which doesnt allow for the use of legacy/stage 1 L1, only stage2
  //so you no longer have to pass in the EDProducer
  //however I set things up such that its an error to try and configure the stage-1 L1 here
  //hence the extra private constructor
  //tldr: use these constructors, not the other two if unsure, if you get it wrong, there'll be an error
  //
  //The last constructor argument declares whether EventSetup
  //information is retrieved during beginRun, during the Event,
  //or during both. This is needed to declare which EventSetup
  //products are consumed. In the future, this will affect
  //when prefetching is done. Declare both and it will always
  //work, but there is some performance advantage to only
  //declaring the necessary one. With only a few exceptions,
  //existing clients call both initRun and accept (the two main
  //functions in this class getting EventSetup data), so EventSetup
  //objects might be retrieved in both periods. The argument defaults
  //to this. The function expressionsFromDB also gets data from
  //the EventSetup and is called by a few clients.
