-Collections of phylogenetic trees, such as those output by Bayesian or parsimony
-analysis, may occupy discrete regions of tree space such that individual
-clusters of trees are separated from all other trees by a certain distance.
-Finding such islands, and taking their consensus, can be an effective way
-of summarising conflicting signal in a phylogenetic dataset [@Silva2021].
