colorscience

WARNING

This package will someday be removed.
I have long thought that it is too big and has some unimportant functions, so I have been copying the important parts to these packages:

colorSpec, with emphasis on spectra
spacesXYZ, for CIE XYZ and derived spaces
spacesRGB, for various RGB color spaces
munsellinterpol, for ISCC-NBS color names and centroids

while improving functionality and documentation. I also added vignettes and tests.

Whenever possible, please use these packages instead.
If there is a feature in colorscience that you cannot find in one of these 4 packages, please let me know.
