get porosity of a packing
Hi,
The problem seems trivial but when I try using `utils.porosity` I can only get something like <Boost.

Will the code take care of these right now? If not, maybe we could do scaling (3D to 2D) outside the code. So this is not a big problem.
Another problem is that the documentation says we'd better use ScGeom in stead of Dem3DofGeom. But as I try using `Ig2_Sphere_
