Creates the PointEvaluator that will be sampled for propagation. Note that it is possible, and sometimes required, to make this PointEvaluator with a different EvaluatorGroup than the one that made this propagator. Do not cache the group that made this propagator, and design your derived propagator to have no undesired side effects or dependencies on the PointEvaluator returned from this method.
