Implement an intitial server based on flask.

Do the core work necessary to have a first response served to a GET
request and some basic wiring to allow submission of JSON via POST.

CHECKPOINT: running coreapi server

overrides? not yet sure why this was needed

Implement a user creation endpoint in the server.

Back a POST handler onto the refactored createuser functionality file which
exposes a function that can be invoked programatically with a configuration.

Split out the response data decoding chunk.

axe depedency pn reworkings on userapi

fixups - move closer to the server working without createuser changes

Implement finding users by email address.
