 *  \ingroup ECF
 *  \ingroup Op
 *
 *  Evaluate Pareto front from demes and vivarium and put it in place of the actual hall-of-fame.
 *  The Pareto front is evaluated just before milestones are written. If previous hall-of-fame are
 *  presents in the demes/vivarium, they are erased. This operator must be in the evolver's operator
 *  sets between the termination criterion check operators and the MilestoneWriteOp operator.
