Brand/Model Support with Minimal changes

[nsonntag]

I have added brand and model support with the goal of altering the existing code base as little as possible. This differs from the approach taken in pull request #4. By making an effort to make only small changes to the code base, the flow and readability of the code remains in tact.

Thank you for maintaining such a great repository. Please let me know if you have any questions or comments.

All tests passing.

Works great. As this repository seems not maintained much, I applied the patch locally. Thanks.
