 Create Occupancy vs event histogram
 (we create this histogram differently then the other histograms
  because this we want to be able to access and copy
  from AliTPCQAMakerRec before it normally would be created)

 Create Nclusters vs event histogram
 (we create this histogram differently then the other histograms
  because this we want to be able to access and copy
  from AliTPCQAMakerRec before it normally would be created)

 Update histograms that display occupancy and
 number of clusters as a function of number of
 events

 Event Processing loop - AliTPCRawStreamV3

  Event processing loop - AliRawReader

  process date event

  Write class to file

 Signal filling method

 This method is called after the data from each sector has been
 exapanded into an array
 Loop over the signals and identify local maxima and fill the
 calibration objects with the information

  Calculate calibration constants

 Export result to the tree -located in the file
 This file can be analyzed using AliTPCCalibViewer

 The arrays for expanding the raw data are defined and
 som parameters are intialised

 Return pad and timebin for a given bin

 This methods return the charge in the bin time+pad*maxTimeBins
 If the charge is above 0 it also updates the padMin, padMax, timeMin
 and timeMax if necessary

 Automatic schema evolution was first used from revision 4
 Code based on:
 http://root.cern.ch/root/roottalk/roottalk02/3207.html

 This has to be filled at the end of the loop over data

 Define the calibration objects the first time Update is called
 NB! This has to be done first even if the data is rejected by the time
 cut to make sure that the objects are available in Analyse

 reset all data

 GetArray with confiured ROCs

 DQM output

 DQM getter

 DQM setter
