Rewriting this for Python3

[faaip]

Hi.

I hope it's ok to submit this issue. I really like these notebooks, but wanted them to run in python3 in order to keep them alive and useful. I created a fork, where I'm slowly rewriting the notebooks and utility functions for python3. If anyone wants to contribute, simply clone the fork and checkout the python3 branch. I'll make a pull request once I've made it through all notebooks.

Thanks for your tremendous work, Kyle.
