Detailed Description

A particle that is the geometric centroid of other particles.

A decorator which constrains a particle to be the centroid of a set of other particles. The centroid is updated before model evaluation and its derivatives are copied to its children, using a constraint that is created at setup time.

Note
The maintenance of the invariant is done by an associated IMP::Constraint. As a result, the state is only guaranteed to be correct either during model evaluation, or immediately following model evaluation before any particles have been changed.
