A first cut at displaying section by section analysis through Django

This makes some assumptions about SXS analysis (namely around how we want to display things). We'll have to clarify these later. Also, the HTML for the notice is obviously not how we want it, but it's a placeholder until the front end folks can take a look at this. 

The URL for accessing a SXS paragraph is as follows: 

http://127.0.0.1:8001/partial/sxs/204-30/2012-1728

The first set of numbers is the regulation section, the second set is the Federal Register notice.
