19 /** RestraintSets allow one to define a tree of restraints
20  and to weight various restraints. Upon evaluation,
21  all of the restraints in RestraintSets that have been
22  added to the model are evaluated
23  using the provided weight (weights are multiplicative
24  when RestraintSets are nested).
25 
26  If the weight is 0, the restraints are not evaluated.
27 
28  \note Restraints can belong to multiple RestraintSets.
29  The total effect is simply one of adding up the weights.
