To bridge Doxygen-generated C++ reference documentation into pipelines.lsst.io, a Sphinx-based site, we know we want to use Breathe. However, we don't know the best way to build out the API reference site. We don't want a monolithic page with all APIs, instead, we want one-page-per-API, like we do the Python docs.
One approach to building out this page hierarchy is breathe-apidoc, a CLI tool that's part of Breathe. This ticket is to demo that approach and see if it's an appropriate solution for the LSST Science Pipelines documentation.
