Three changes

Hi Rob!

Three changes:

1. There's a python function to return a frequency distribution of all the non-stop words used in the reflection. It's called generate_popular( ) in reflection_scraper.py
2. I added functionality that when you click on a matched person's name in the wheel, it displays snippets of their reflections that included that word
3. I fixed the name submission system so that pushing enter only calls the generate tree function once. Before, hitting 'enter' ran the function twice

Brief expansion on 3 for Rob's benefit, as he wasn't here for the conversation:

html already submits a form when enter is pressed. Thus, it's not necessary to handle the submit via button and keypress separately in jQuery. Simply calling generate_tree upon "submit" works in both cases.
