20 Based on AliPHOSQADataMaker
21 Produces the data needed to calculate the quality assurance.
22 All data must be mergeable objects.
23 P. Christiansen, Lund, January 2008
29 We have chosen to have the histograms as non-persistent meber to
30 allow better debugging. In the copy constructor we then have to
31 assign the pointers to the existing histograms in the copied
32 list. This have been implemented but not tested.
