Locator map + vector tiles

Automatically adding some extra context (major cities and interstates) to a county map with MapZen vector tiles.

Downloads the tiles to cover the entire bounding box at a medium zoom level, stitches together the road segments, and filters down to major interstates (e.g. I-5, I-80) and large cities with some minimum spacing between them.

This would probably never be practical at all! Downloads a ton of unused data and the results for any random place aren't totally predictable.

Potential improvements: dynamic label placement, adding rivers
