Reuse axis titles in 2D profile from the original 3D one
StiScanHistContainer: Now use custom 3D profiles for Eloss and RelRadLength histograms
Reordered parameters in StiScanHist... constructors
Added a flag to switch between (integral) projection and (average) profile when reducing dimensions of 2D profiles. The latter is default
Added some functionality from newer TProfile2D class which is not available in our current ROOT version
Profile3D: Use local Profile2D class instead of the ROOT's TProfile2D
StiScanHistContainer: Removed unused class method PrettifyHists
tevedisp: Removed dependance on ROOT's tutorial macro MultiView.C. It is not available in recent ROOT version and is not really used in this code
