Is it possible to separate binning and bincontents?
- this would be a small revolution and an important step towards inheritance from TH1
- it means separating the way how the binning is created and the rest of the code
- maybe we need to go the extra mile and create the binning, but fill histograms in a subsequent step
- get rid of class template with this
- get rid of constructing from histograms?
- get rid of TH2X members
- this might need a class within TH2A....
