Niels Lohmann 7b2a1b2de5 Docs: fill documentation gaps found in user questions
Add pages on class-hierarchy/smart-pointer/variant/chrono recipes, working
without exceptions, and large, streamed and partial input. Extend the FAQ
(23 entries, Known bugs first), parse error documentation (empty-input
checklist, line/column, diagnostic positions), element access, conversions,
creating values, ADL troubleshooting, memory, and build/distribution notes.
Add 14 examples with generated output. Correct the statement that parse errors
cannot be recovered from with -fno-exceptions.

The topics come from recurring questions on Stack Overflow, Reddit, Hacker
News, YouTube, and the project's GitHub discussions and issues.

Generate documentation

Note on documentation: The source files contain links to the online documentation at https://json.nlohmann.me.
This URL provides the most recent documentation and also applies to previous versions. Documentation for deprecated functions is not removed; instead, it is marked as deprecated.

If you want to view the documentation for a specific tag or commit hash, you can generate it locally as follows (example using tag v3.12.0):

git clone https://github.com/nlohmann/json.git
cd json
git checkout v3.12.0
make install_venv serve -C docs/mkdocs

Open http://127.0.0.1:8000/ in your browser. Replace any URL in the source code that points to https://json.nlohmann.me with http://127.0.0.1:8000 to view the documentation for the selected tag or commit hash.
