O.bodies[0].mold['radius'] (if it is a sphere, otherwise you get
KeyError).

The confusing thing is that InteractingGeometry is called "mold", based
on my original simplification proposal: GeometricalModel->Shape,
InteractingGeometry->Mold; since GeometricalModel is gone now, let's
call it geom. It is more readable and there is no problem having both
anyways.

I added a "geom" alias for mold in last commit, so you can use
O.bodies[0].geom['radius'] instead.

PS. You can test sphericity in several ways:

if O.bodies[0].geom.name=='Sphere' # test name of the InteractingGeometry instance
'radius' in O.bodies[0].geom.keys()  # tests presence of the radius attribute
if O.bodies[0].geom.has_key('radius') # this one should be a little faster

Cheers, Vaclav
