Add a quick note about authn/authz server requirements.
Put together an experiment:

	- A start to an authn/authz API and implementation
	  for use inside/alongside nginx, based on the ideas
	  described in the top-level README.

	- Implemented a boilerplate Django application that
	  provides a hook to allow the authn interface to
	  check request credentials.

	- Wrapped a simple nginx internal service with this authn
	  API, without it needing to be aware of any of the
	  Django authentication process.

This amounts to a slightly more functional version of the
already existing 'auth_request' functionality.
A quick README describing how to launch this example.
Apparently I don't know my native language.
Clarify what we're doing.
Add additional explanation.
Typ-o.
Add a simple Flask-based echo server.
Bind in another HTTP-based service.
Start sanitizing incoming requests, by stripping X-Tauth-* headers.
Use normalized case.
We should be optimizing authn and authz in the same request, where supported.
Reformat.
Add support for the authz API.
Continue fleshing out hooking up authz.
Add first-round checking of authz.  Support minor
changes to the authn API.
Turn on authz checking.
Unauthorized is not an internal server error.
Updated to support authz.
Quiet things down.
