class(ClusterSeed) instead of class(SageObject). Also allow
ClusterTriangulation.mutate method to mutate a self-folded triangle's
radius r. This mutation method is not quite an involution because it you
mutate r twice you will end up with the same (unlabeled) triangulation but
the label of r and the loop are switched.}}}||
