Measures the degree of balance for a given phylogenetic tree by
calculating the Total Cophenetic Index.

A new balance index for phylogenetic trees.

The total cophenetic index describes how balanced a phylogenetic tree is, by measuring the how deep the most recent common ancestor of each pair of leaves lies within the tree.
This functionality is now available via Rogter's package https://github.com/LuciaRotger/CollessLike R package.
