Test if taxa are "internodes" in a taxonomy() or taxmap() object. An
internode is any taxon with a single immediate supertaxon and a single immediate
subtaxon. They can be removed from a tree without any loss of information on
the relative relationship between remaining taxa.
obj$is_internode() is_internode(obj)
Arguments
