Improve location disambiguation beyond purely GPS coordinates

[liuche]

Before Hawaii, we made the decision to switch to GPS coordinate matching only (discarding location name) because the Yelp location search was made worse by adding the location name. Now that we've finished that trial, we should find ways to improve that matching (e.g., through fuzzy name matching, etc)

For reference – 

1. neither Yelp nor Eventful's location data are especially accurate (e.g. up to a mile between a venue's location as found in Eventful versus Google Places).
2. yelp's name + location search often returns nothing.
3. Google Places API sometimes returns good results, but not others.
4. Factual Crosswalk provides Eventful IDs, but not much Yelp data.

This is a generalized problem, and worthy of discussion with the Context Graph server team.
