Voronoi sphere

I'll add a `voronoi3d` module to [dotSCAD](https://github.com/JustinSDK/dotSCAD) for creating a 3D version of the [Voronoi diagram](https://en.wikipedia.org/wiki/Voronoi_diagram). This is how you can use it. The preview or rendering of 3D Voronoi takes time, so the source code doesn't create the Voronoi sphere directly. You have to download the scad file, open it with [OpenSCAD](http://www.openscad.org/) and render the 3D Voronoi model first. Then, update the `stl_file` in the scad file to the stl filename. Open it again with [OpenSCAD](http://www.openscad.org/), render and export the final model.
