Implemented layout

Basically put in the new layout. Some of the hovers aren’t exact, but I
think I want to change some things, so I didn’t bother fixing it.

What I plan on changing when I wake up in the morning:
- make the airline button filters a little smaller since they look a
little cramped.
- make the airline icons in the info box a little bigger, since they
look a bit small.
- the text looks even smaller on the vis so I will try to think of a
way to display that bigger/better
- fix the info box graphic. if you look closely, you’ll see that the
black background does not span the entire box. oops.
- add the intro text to the bottom of the vis.
