Dummy methods of Builders appear in documentation
In !182 (merged) we add dummy methods to
Builder to tell users when they should finalize their systems.
However, these methods also appear in the documentation for
Builder, which is confusing.
I am not sure how to tell sphinx not to document certain methods, as all of the reference documentation pages are generated automatically using
autosummary. Probably we will have to dig our hands inside sphinx (again).
