This PS adds tooling and automation to automatically generate
Shipyard's documentation into feature-rich HTML pages that can
be hosted.
To run the documentation job, simply execute:
tox -e docs
Shipyard's .md documentation will have to be changed to .rst
in a future PS for sphinx to be able to render them into HTML.
