a client for buses and trains

An alternative client for WMATA data.

The goal is to make WMATA's API something that you could use without worrying about constructed Mashery API key limits, and that's way faster and more convenient.

The client is very limited thus far. It refactors things that should not be on the server side into things that are not on the server side.

// find a rail stop near a lat, lon 
// and an entrance 
// and a bus stop 

Stop-finding is based on a static export of the station data and sphere-knn.
