-- -- | An evolutionary label has some information about where the corresponding
-- -- node is on the tree, and if the node is 'extant', 'extinct', 'internal', or
-- -- 'external'. The latter two could also be determined from the tree. This could
-- -- be species, genes or individuals; probably more.
