Agree it is just whitespace only changes and ends of files!

Just a thought - at the software sustainability hackathon we discussed ways of keeping track of who had authored/changed what part of the code for licensing/copyright reasons. PRs like this make it difficult to keep track through git. I don't know what we agreed?

I believe we should also discuss about coding standards. I think these changes are applied by your code editor or other tools to abide to some coding standard.

It would be better if we used such tools when developing. I don't know if the pre-commit that is in eqt is what we want, though?

I intend to squashmerge this with a bot username (@github-actions[bot]) plus ignore the commit so it's not associated with my user.

Also yes long-term we need an eqtesque solution in cil, but that's blocked on TomographicImaging/eqt#98
