Overview

This pulls the VectorTile generation out of RDD-land by defining some case classes (and some ugly Value conversion) that Spark can serialize automatically.

Notes

When I benchmarked this (lightly), runtime was similar to the RDD-based approach but Spark was able to show me a concrete plan.

There are similarities in approach and goal to bits of #93.
