1) use multiple hierarchies, see the custom_hierarchy example fragment
(or the HiearchyTraits docs) for how to do this
2) use a TableParticleRefiner. It is pretty straight forward, but was
just written, so you mileage may vary

hi,
So , I have a molecular with proper hierarchy, and would like to add
rigid bodies.
To define the rigid bodies I am using molecular hierarhcy, so a
particle may have more than one parent ( one for the molecule, for
example an atom belongs to a molecule, and one for his rigid body).
Currently a particle can have at most one parent in molecular hierarchy.
I think the solution should be adding RigidBodyHierarchyDecorator -
thoughts?
