This is an implementation of a quad tile tree. It can be used to quickly lookup POIs for representation on a map.
The idea is based of an article by OpenStreetMap as well as Microsoft, I'm not sure who was first.
There is no good API documentation, but usage is pretty simple: add to add
things to the tree and get to look them up.
add takes a {lat, lon} object and some arbitrary payload.
get takes a {x, y, zoom} tile and will return all objects within.
See the example code for more.
