Updated Annoy Tutorial with Text8

[pmbaumgartner]

Updates:

• Runs in python 3
• Added required packages (in addition to gensim) to top of notebook
• Cleaned up some descriptive language throughout the notebook.
• Used Text8 Corpus rather than Lee corpus, since I wasn't seeing an improvement using the Lee corpus. My hypothesis is that it's too small to see any benefit from approximating.
• Added watermark info for benchmarking comparisons
• Reorganized and restructured notebook
  • Added an outline according to the logic of the notebook
  • separated notebook cells for import, function definition, and executing code
  • Added optional logging
  • Combined num_trees performance analysis into one loop & plots into one figure and upped num_trees to 300

Thanks a lot! Let's keep the old name and replace the Lee corpus ipynb with this time.
