Chapter 1 examples no longer work about fopnp

This seems to be working for me now. Just required pip installing geopy (and requests, for search2.py, which was already needed in the old examples).

Thanks for updating!

Thanks for letting me know! I'd prefer to point users at a different service that doesn't provide API keys. When I get the chance, I'll search to see if there are any geolocation services that don't require one yet.

Thanks again for pointing out that these scripts were broken. I've rewritten them (well, the Python 3 examples; I'll leave it to another contributor, maybe at a conference sprint sometime if not before, to translate them to Python 2) to use the Open Street Maps project — let me know if you have any trouble now that they're pointed at another service!
