Generates a default node-label function
Is not a labeling function itself, but returns one.
The returned function is capable of adding
whatever label is on a node. Note that the function that
is returned has two completely different arguments to those listed here:
the plot object already built by earlier steps in
plot_tree, and the data.frame
that contains the relevant plotting data for the nodes
(especially x, y, label),
respectively.
See nodeplotboot for a more sophisticated example.
The main purpose of this and nodeplotboot is to
provide a useful default function generator for arbitrary and
bootstrap node labels, respectively, and also to act as
examples of functions that will successfully interact with
plot_tree to add node labels to the graphic.
nodeplotdefault(size=2L, hjust=-0.2)

(Optional). Numeric. Should be positive. The
size parameter used to control the text size of taxa labels.

node labels. Default is |
A function that can add a node-label layer to a graphic.
