Dev server example for a Flask + Client-Side App

"""
We have a little all-api python application that will have a client-side front
end and needed a script to run a dev server. This is it.

The app itself is a flask app, and will be mounted at `/api` in production. This
is an example of how to reproduce a setup like that with Werkzeug and Static.
