Priors would be links that will never get deleted during reduction by any model.
The easiest way to support priors would be by utilizing an additional integer type attribute "prior" in the attribute table of the precomputed links map passed via "initial=". Granted, this would leave the burden of how to get prior link representations into the initial map on the user. But it would also greatly simplify program logics and reduce interface bug potential.
