Package auth contains user authentication code for webservers.

Basic access authentication requires a client to provide a user name and password
with each request. Most browsers will directly support this method.
See: https://en.wikipedia.org/wiki/Basic_access_authentication

Cookie based authentication requires the client to login once and create a unique
access token. The access token is then used to authenticate each request.
