Add clang-format

[DeveloperPaul123]

This clang-format was created using LLVM's tool to "detect" the format from existing code. From my testing, it's quite close.

Hi @DeveloperPaul123!

Please could you submit these changes as two separate PRs? The .gitignore update looks good and I'll commit it right away, but I want to try out the clang-format file first before deciding whether to add it (I've found that clang-format destroys my hand-crafted nice formatting as often as it fixes things...)

@tcbrindle Seems reasonable! Done in #111

@tcbrindle Any comments on the clang-format? Or any formatting changes you'd like to see in the config file?

[tcbrindle]

I do like the idea of having a project-wide clang format config to keep everything consistent, and to make life easier for new contributors.

The only problem is that I'm very fussy when it comes to how I like my code formatted!

I still need to have a play with all the clang-format options until I find the combination I like.

[DeveloperPaul123]

I completely understand. If you have examples of styling that you want to keep that clang-format is breaking, feel free to post them here and I can try to update the clang format file.

While contributing on #192, at least half of the reviews were about formatting. This creates work for both the contributors and the maintainer(s) that could be automated. I understand your desire of keeping your code formatted exactly as you like, but I think this is a case where consistency and automation beat preference. I'm willing to update this PR if needed. Would you consider merging it @tcbrindle?

[DeveloperPaul123]

I honestly forgot this was still open. I'm also happy to address any concerns to get this merged in.

[tcbrindle]

I've finally added a .clang-format config for the project in PR #199. Thanks @DeveloperPaul123 for the initial work on this and @Guekka for reminding me that I should actually do it :)

[DeveloperPaul123]

No problem 👍
