[documenter] From Notebook to Markdown with docstrings?

An update for people stumbling onto this older post, if your aim is to have one set of documents for updating that can be used as both Jupyter notebooks and source for documentation then Literate.jl is probably the way to go, as mentioned by @fredrikekre , at least that is the solution we are likely to use moving forward. It’s really easy to use, and there’s no use case I can think of it doesn’t cover.
