Elevating this, we have a lot of data in the app and need to document sources and "last updated". This could live in a markdown file somewhere outside of the app, but should be updated whenever new data are loaded.

• Add a new route for a data listing in the top level nav (/data)
• Add new meta properties to the layergroup configs to populate the data route.
• (title, description, link to data source, updated_at)

It's occurring to me that we are going to need to have multiples in some of the meta properties. Example, the subways dataset is two shapefiles, one for stops and one for routes. Furthermore it's a frankenstein of data from DoITT and Baruch College.
