 This package provides tools for working with [Gustavo](https://github.com/niemeyer) [Niemeyer](https://twitter.com/gniemeyer)'s [geohash](https://en.wikipedia.org/wiki/Geohash) system of nestable, compact global coordinates based on [Z-order curves](https://en.wikipedia.org/wiki/Z-order_curve). The system consists of carving the earth into equally-sized rectangles (when projected into latitude/longitude space) and nesting this process recursively.
