MuonResonanceTools Fix, master branch (2020.09.30.)
This update is meant to fix ATLASRECTS-5675.
The most important part of this update is the addition of an .ignore() statement to one line of MuonResonanceSelectionTool.cxx.
But to find the source of the issue described in ATLASRECTS-5675, I also had to make it just a little easier to debug problems with CP::CorrectionCode objects. For this purpose I added a ROOT dictionary for this type. (I was utterly surprised that we didn't have one already. @krumnack, how have we not run into problems with this before?
