[IMP-dev] more than one molecular hierarchy

[Keren Lasker <kerenl@salilab.org>]

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?
thanks,
Keren.
