New histograms (qa::H1D, qa::H2D, qa::Prof1D, qa::Prof2D) in the online reconstruction QA
Features:
- new 1D- and 2D-histograms based on boost/histogram (with working example of 2D-histogram in the CA online QA)
This merge request introduces modifications to:
- online digi-event builder QA (replacement of Histo1D with qa::H1D)
- online tracking QA
- histogram server (added 2D histograms)
- histogram server tester (message initialization is now carried out with the qa::Data class)
@p.-a.loizeau, please, take a look on the histogram server part
Update:
- the classes qa::Prof1D and qa::Prof2D were added (the example - hit usage in different tracking stations)
