- Need a trivial way to create a self-contained notebook, given small-ish repo. The point would be to obviate the need to set up a project, etc—once you have the notebook, you have everything. (Likewise, consider a way to ingest these notebooks and convert them to Inaft-style tests.) As a basic example, consider if we wanted to demonstrate a polyline decoding routine.
