Notes

This is necessary to get a testing instance up on Digital Ocean.
Allows the client to jury-rig the creation of documents, since there is no file management.
When CouchDB auth env. variables are set, the auth is proxied via
- PouchDB when secret headers are authenticated in the middleware, and
- injecting a basic bearer auth header before /db requests are passed downstream to the proxy.
