A poet does TensorFlow

After reading Pete Warden's excellent TensorFlow for Poets, I was impressed at how easy it seemed to build a working deep learning classifier. It was so simple that I had to try it myself. I have a lot of photos around, mostly of birds and butterflies. So, I decided to build a simple butterfly classifier. I chose butterflies because I didn't have as many photos to work with, and because they were already fairly well sorted.
