v1.0.1 (2014-Jul-03)
* Added/verified Python 3 support and tests (3.2+).
* Added support for sending a DRF authorization challenge if we're the primary authenticator.
* Switched to using the `httpsig` HeaderVerifier instead of doing it ourselves. Lots of code got deleted there.
* Changed fetch_user_data to also receive the algorithm the keyID is for.
* Updated README.
* Removed models.py -- the client should handle that part entirely.
