Quadtree Madness Round 2

So hit the button in the bottom left to start adding points, then if you hold down shift and draw a box it'll running a bounding box query on that area and limit the map to that. Hit the other button in the bottom left or right click to remove the query and show all of the markers. I also did versions with Icon Markers and Marker Clusters
