Truncated, geocoded data for ex2_googlemaps.py

I have geocoded the locations of 100 Walmart store openings in http://www.econ.umn.edu/~holmes/data/WalMart/store_openings.csv. These are the first 100 store openings from the complete dataset constructed by Thomas J. Holmes, University of Minnesota and available at http://www.econ.umn.edu/~holmes/data/WalMart/store_openings.html.
