Provides easy access to, and manipulation of, the Munsell
colours. Provides a mapping between Munsell's original notation
(e.g. "5R 5/10") and hexadecimal strings suitable for use directly in
R graphics. Also provides utilities to explore slices through the
Munsell colour tree, to transform Munsell colours and display colour
palettes.
