  Based on AliPHOSQADataMaker
  Produces the data needed to calculate the quality assurance. 
  All data must be mergeable objects.
  P. Christiansen, Lund, January 2008

  Updated July 2011:
  ==================

  Major changes to accomodate updates of general DQM/QA changes to have per
  trigger histograms (for a given event specie).

  1) One instance of AliTPCdataQA only. (This also solves some old wishes by
  offline team to use less memory because event the 2d arrays for this object
  is not used). This now has a new flag for only keeping DQM info event by
  event! For this reason there is no need for a special DQM reset any more
  between runs!

  2) Fill the histogram for each event. The histograms are no longer filled
  from the AliTPCdataQA but per event.

  3) Use profiles for the RAW info. By adding the profiles event by event we
  get the correct event averages WITHOUT having to normalize in the end!
  Results should therefore also be directly mergable when that feature will
  come. (none of the other histograms are merged).

  This means that from the DQM/QA point of view the TPC DQM is now fully
  standard and should ease future developments.

  Updated June 2010:
  ==================

  The "beautification" of the online DQM histograms have been moved to
  an amore macro.  

  The per event RAW histograms have been modified in AliTPCdataQA and
  the copies have therefore also been modified here.

  The AliTPCdataQA can now be configured a bit from here: time bin
  range (extended default range to 1-1000, event range at start:
  0-100000, 1000 events per bin). (At least the parameters are not
  hardcoded:-)

  Implementation:
  ===============

  For the QA of the RAW data we use the class, AliTPCdataQA, from the
  existing TPC Calibration framework (which is more advanced than the
  standard QA framework) and extract the histograms at the end. The
  Analyse method of the AliTPCdataQA class is called in the method,
  EndOfDetectorCycle, and there also: 1d histogram(s) are projected
  and added to the QA list.
