Review documentation demos #1102
Description
We should be more selective about which examples we link to directly from the mrdocs website. In particular, we have things like fmt, which have very little documentation. It does not look good. We want to showcase a library with extensive Javadoc. Clang/LLVM, for example, has plenty of documentation comments.
Pages like this aren't doing us any favors: https://mrdocs.com/demos/develop/nlohmann-json/multi/adoc-asciidoc/nlohmann/to_string.html
