AssertionError when C++20 Concepts are present

MCSS, specifically the mcss fork that Poxy uses (the issues tab isn’t present on the fork), compares each fundamental element type against a list (doxygen.py, line 3222) including struct, enum, etc. As concept isn’t present, the chain of comparisons ends up at the else condition, which simply asserts False and crashes the entire documentation generation process.

I would appreciate concept generation being added, but I’m also happy for the else condition to simply ignore unknown element types (generating a warning instead of asserting False).

If it’s rainy enough over the weekend, I could look into adding concepts support into m.css. Was one of my TODO items for Doxygen 1.9 support, apart from everything else in https://github.com/mosra/m.css/issues/215.

No promises though 😛

@jake-arkinstall as of v0.9.0 support for C++20 concepts has been implemented 🎉

You’ll need to add 'concepts' to your navbar option for the index link to show up, but search and auto-links will work out-of-the-box.

Note that it’s an evolving story as they’re not even merged into m.css yet (I have a PR for that), so the way they’re presented or organized might change a bit over the coming versions. Happy to hear any feedback.
