Research direction

Start with docs/sphinx-build.sh and the generated files under docs/source/api, especially methods_database.rst and scripts.rst. Trace how sphinx-apidoc output is modified for the YAML templates docs, then run the documented sphinx-build command to reproduce the warnings. Done means the YAML templates documentation still builds and the unused API files and import warnings are removed.

Description

documentation

As noted in https://github.com/DiamondLightSource/httomo-backends/issues/10#issuecomment-2443698342, the YAML templates docs are dependent on sphinx-apidoc. More specifically, the rst files generated by sphinx-apidoc (which is a tool for generating API docs) are modified after sphinx-apidoc runs, in order to produce the YAML templates docs.

This approach works decently, but one downside is that API docs are being generated for everything in httomo_backends/ (none fo which are python packages or modules, there's only some standalone scripts), and so when the final sphinx-build command is run in sphinx-build.sh, there are some unused API docs rst files that causes some warnings to be outputted:
