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

  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.
