v1.1.1

Adds support for logging out of the local CAS session.

Previously, there was no way to force the local session to terminate except for the timeout expiring on it's own. This allows the specification of an endpoint that will terminate the user's session, and, optionally, log them out of the CAS service itself.

Additionally, the README has been converted to Markdown and has additional details about development as well as aspects describing the above change.
