Create new ActsTrkEventCnv package, and copy ActsATLASConvertorTool there
This is my first attempt to improve the ACTS convertor.
As a first step, I don't think it belongs in ActsGeometry, so I made a new ActsTrkEventCnv package.
I also renamed some code - I don't think we should talk about "ATLAS tracks" etc, since:
- ATLAS has several track types, so this is ill-defined
- one day ACTS tracks should become default, and then they will be ATLAS tracks
- Athena already has one "non-ATLAS" client (FASER) and it would be great if we had more.
So, I changed ATLAS to 'Trk' (in the end it's the Trk:: EDM we're converting)
I also renamed and cleaned up some methods to match ATLAS coding standards (i.e. don't capitalise the first letter of functions).
I added a new TrkToActsConvertorAlg, which doesn't do much yet but should one day convert TrackCollections into Acts::TrackContainers
Added a new test to run the above, and copied a RUN4 ESD to cvmfs to use for this test.
If this is agreed upon, then the next steps could be:
- remove the old convertor and update clients
- add a track conversion method to the tool
- implement a closure test (convert to Acts tracks and back again, and compare the result)
