MakeTreeBinary() resolves, at random, all polytomies in a tree or set of
trees, such that all trees compatible with the input topology are drawn
with equal probability.
Arguments
- tree
A tree of class
phylo.
Value
MakeTreeBinary() returns a rooted binary tree of class phylo,
corresponding to tree uniformly selected from all those compatible with
the input tree topologies.

Since ape v5.5, this functionality is available through
ape::multi2di(); previous versions of "ape" did not return topologies
in equal frequencies.

#>
#> Phylogenetic tree with 7 tips and 6 internal nodes.

#> Rooted; no branch lengths.
