Renamed SQLAlchemyBinding to SQLAlchemyMixin. Worked SQLAlchemyMixin so the models can be defined without being mapped right away.
Working on creating tests
Got Mock object for pySerial working
Changed the read_RFID internal data variable to a property with a redefined getter and setter. The data property checks when set if the it's size is greater than 41 and set's itself to an empty bytearray if that's the case
Added in another assertion for the data property test and added in some comments/docstrings
Added in more tests
Release candidate

- Updated models to give the ability to "disable" cards. This way can
  can see keep cards attached to the user and still revoke them access
- Added in some more test cases, still not perfect but it's a start
- separated the SQLAlchemy database setup/tear down code into it's own
  class (now called SQLAlchemyBase). This way we can use the can code
  for scripts that use the base daatabase structure but are separate
  applications
- General code clean up and fixes
