+ * Not storing the entire user in the session anymore (which was convenient
+ but bad practice) but only its __dict__.
+ * As a result of the above, the get_current_user call is now gone and
+ replaced by get_current_user_data call. Similar functionality to the original
+ call can now be obtained by doing AuthUser.load_current_user().
+ * Created SQLAlchemy plug-and-play model using constructor.
Added tests, permission example, bunch of bugfixes.
