quadtreejs v1.0.0

#QuadTree One of the sexiest data structures around. This one's written in ES6 but compiled with traceur, so it should run anywhere.

##Point QuadTree When points are accurate enough.

##Region QuadTree Great for 2D collision detection, image mapping, and a lot of other shit you can read about on wikipedia.

##Use the width and height of the space you wish to partition so eloquently along with the max depth and max objects per space.

    var tree = new QuadTree(width, height, 100, 5);
    tree.insert(item); //where item is an object with an x and y value.
    tree.retrieve(item); //where item is an object with an x and y value.
    //retrieve returns all objects which could collide with item

insert can also take arrays. Because that's useful.
