José announces Livebook - a web application for writing interactive and collaborative code notebooks

While reading the discussion Is there a complete Elixir AST reference?, it struck me that Livebook could be a really powerful tool for generating and maintaining documentation (with executable examples!) for this sort of thing.

That said, there are some convenience features that might be useful for this and similar use cases. For example, it would be nice to have automated generation of a Table of Contents, as seen in Wikipedia.
