Omit explicit import of TIter since this triggers cppyy to fetch the class upon importing ROOT. Acessing TIter through cppyy.gbl.TIter does the same job lazily.

If the comment is left in the code, the html documentation renderer shows it
as part of the next member function which is misleading.

...and add test coverage

Default GDML import units restored to Geant4 ones. Can be changed before import using TGeoManager::SetDefaultRootUnits().

This is to avoid direct linking to TBB in e.g. libTree,
since TBB should be encapsulated by libImt.

This is to avoid direct linking to compression libraries
in libraries that link to libCore.

Without using '^' and '$', the regular expression also
matches things that contain the keywords, like FILESYSTEM.

The following example shows the improvement.

{
   auto h = new TH1F("h","h",5,0.5,5.5);
   h->SetBinContent(1,100000);
   h->SetBinContent(2,10000);
   h->SetBinContent(3,1000);
   h->SetBinContent(4,100);
   h->SetBinContent(5,10);
   h->SetMinimum(50.);
   h->SetMaximum(40000);
   h->Draw("L*");
   gPad->SetLogy();
}

It is equivalent to gStyle->SetHistMinimumZero(1), 
but can be specified individually for histogram

For the moment it is just  gStyle->GetHistMinimumZero() value

Fix the exclusion of underflow bin (and include the last bin) when computing the shortest interval in the BayesianCalculator  (#3402)

* fix a bug in excluding underflow bin when computing shortest interval in BayesianCalculator::ComputeShortestInterval. This fixes problem reported in ROOT-4619

* update refeerence file for changes in Bayesian shortest interval after bug fix

* Revert "update refeerence file for changes in Bayesian shortest interval after bug fix"

This reverts commit d51c85a5ac1a32161d6e66d10b9426d242591d0c.

* Add another fix in computation of the shortest interval in the BayesianCalculator. 

- The computed interval was shifted by one bin. 
- The reference file did not need to be updates since the reference results are hard coded and taken from a paper.   
- Add now a new method returning the histogram approximating the posterior.
- Increase the number of bins when computing the posterior histogram in stressRooStats
