Completed visualization

Basic visualization is done. 90+ routes mapped on the screen. I still
need to do five things:

1. change the opacity to .1 or .2 so that the spread between limited and
popular routes is more pronounced
2. correlate the thickness to # of trips/100. The most popular routes
will be 20px, the least popular will be around 3
3. calculate a route delta between the flying crow distance and the
projected route from Google
4. take a damn screen shot so that I don't have to run this thing all
the time to share it with people :)
5. reset the zoom when the animations are done
