Adding attributes

Fixing #21
@ethanresnick @grungerabbit

Same drill as ship-site:

Please check! Primarily I was just going to flatten the attribute structure in the JS file. I ended up just adding attribute tags in the index.html instead. I thought going forward because we're changing the structure permanently this would be better.

@AbhiAgarwal I agree that adding attributes in the code/html, rather than trying to flatten, was the right approach!

On a very quick first pass, this code looks good to me, but @grungerabbit knows the setup much better, so I'll let her do the final review/checks

I'm going to merge this
