Initial code commit

Just enough to get going (basic styles, a web UI, etc.)
Add Godeps and a Procfile to get set up for Heroku.
Fix the letter-spacing on the 404 text.
Change placeholder instructions for point data.
Clean up some styles and make it purtier.
Add supporting code to check whether or not the point is contained.

Relies on the gogeos lib, which wraps geos.
Big fat lazy UI update.
