PAVÉS should support colormaps using the somewhat-standard Matplotlib API which is also implemented by a large number of third-party colormap libraries and collections.

Specifically it should use the colors attribute of a provided colormap to assign a new color to each new label encountered when displaying objects with pi.box or pi.mark. This should be complementary to the existing dict-based color assignment feature.

It should also have a built-in colormap that it uses when no color argument is provided.
