Merge pull request #9 from dclowd9901/master

- Removed floor in 'subdivide' function. When trying to build quadtrees in applications with high precision (a google map's lat/lng measurements, for instance), this was causing the quadtree to never create more than one subdivision or point, unless, of course, the points were far enough apart to pass the bitshift operation intact

cleaning up formating. Node functional code changes.
