Get estimated travel times using Python and Google's distance matrix

Get_estimated_travel_times.py

# You could use this script to map the estimated travel times of a day in the future
# To plot grpahs you could use: http://plot.ly

Can you get for like the past month. I mean it gives you the time taken for the past month
