Slicing geojson into .mvt

A tool that transforms geojson to filesystem pyramids of mapbox vector tiles (.mvt) using node.js.

This involves transforming geojson → sliced JSON tiles → protobuf (.pbf) → serialized pbf (now .mvt) arranged as directory/x/y/z. The benefit to using this over other tools is that it doesn’t require leaving node.js. In the future, I’d like to allow it to produce complete .mbtiles entirely within the browser.
