Getting the application to deploy to heroku

Not a lot needed to change in order to get this up and running.

1. The keys for the Google Maps API and the ID of the Fusion Tables Document needed to change.
2. I moved the contents of htdocs out into the root of the project and added an empty composer.json for Heroku deployment.
3. The JavaScript is all concatenated together and minified in order to go into production deployment, in the meantime we're loading the assets individually.

The app is breathing... But there is a lot of Chicago -> Nashville conversion that needs to take place. If I try and run directions right now, it wants to place me at Harding Pike in Chicago.
