Folks, I need help with the tests and the clang format. Not sure what is going on. Please help me either with pointers or do feel free to add commits to the pull request. Thanks so much in advance!

This is ready for review.

[Rudd-O]

Thanks for the review. All review suggestions were accepted. PTAL @jesserockz .

[Rudd-O]

Strange. No review comment was unaddressed.

[jesserockz]

Thanks for making the changes

[Rudd-O]

Despite the approval, I can't merge this — or maybe the UI will allow me to merge once the tests finish. Will wait a little longer.

No, you cannot merge, only people with write access can merge (like myself) which is done when both code and docs are approved
