Compute inertia tensor? #64

It would be nice if the lib could compute the inertia tensor of each hull at the same time it computes volume.

Bullet's convex hull inertia tensor computation seems to treat all the mass as if condensed in the vertices, so the inertia is innacurate, mostly on elongated objects.

The inertia tensors's three coordinates of each hull could be output perhaps in a text file.

Thank you for reading this feature enhancement petition.

Have you had any luck on this front? I am importing some meshes into a simulated physics engine and I need some reasonable inertia tensor for this purpose.
