Thank you - the example is indeed complex and, because of that I believe it could be beneficial to others. I agree with you that some way to capture 3rd party samples would be better. I'm not sure if listing a link in the main README page is a good idea though. I believe we should probably polish the README for the `samples` folder and put this link in there (plus other, as I know there have been many real-life panama examples, such as this - would be nice to capture them all in one place).
