.node.depth
computes the depth of a node as the number of tips
which are its descendants. The value of 1 is given to the tips. node.depth.edgelength
does the same but using branch lengths.
node.height
computes the heights of nodes and tips as plotted
by a phylogram.
node.height.clado
does the same but for a cladogram.
