Show neighborhoods that a route itinerary goes to

[elliottwilliams]

We discussed geocoding station coordinates to produce "neighborhood" or "sub-localities" in propershark/proper#2, but decided that it would be better implemented in Shark.

I propose that we should show neighboorhoods or local landmarks that a particular route is headed towards. This information is useful in addition to a route or system map, because it allows for useful "heading towards" bylines on a list of routes or vehicles. For example:

Station: BUS123
============

Arrivals:
- Route 1A (#123)     in 2 min
  towards Downtown Lafayette
- Route 5B (#234)     in 5 min
  towards Wabash Landing, Happy Hollow

Following the logic I explained in a comment on #15, this should be implemented as middleware, since the data that is being sourced requires information about a Vehicle.

With that, an interesting question is raised about how middlewares can modify the list of attributes that an Object has. See #20 for more information.

Since #20 has been implemented, there shouldn't be any structural obstacles to implementing this.
