Mesh check error printout

[hajdik]

Purpose

This changes the logic for error printouts for boundary condition checks and topology errors so all errors present in the mesh will print out. The previous behavior was to exit on the first issue, making it hard to fix multiple errors at once.

I also changed the printout that shows up at the start of a case. Originally it printed the case name as the name of the input file, but when running pyHyp with patch input there's no input file. I changed this to print the output file when there isn't an input file.

Do you have a mesh that we can add as tests that catch these cases?

I think I could find one that captures one of the errors somewhere in my computer backup but it's ~800k cells, probably too big for the tests. I never had a mesh that would trip all of the errors at once.

Would also be good to add printout to the PR description.

Are you saying to add the text that I added for the error printout so it's documented here?

Wow, if the input meshes are this large, then yes this is way too big. I was hoping for something manageable to improve testing. Right, triggering everything with an actual mesh is probably not realistic, and we probably need to do this in smaller pieces, or manufacture something. Ideally, we should unittests this, although this will take a lot more effort. Given that this is not a runtime critical application, I am approving for now. But if you have other ideas, feel free to create an issue or update this PR.

Yes, I was just thinking of some type of documentation here as to what is expected as I dont have anything to run this with.
