[Rd] New grDevices::hcl.colors()

[Achim Zeileis]

Abs,

thanks for the feedback. As you noticed meanwhile we had linked Ross's 
2003 paper as well as a few other references. The slides from Ross are a 
useful addition, I didn't know these (only parts of them).

Also we didn't want to list all of the references in the blog post but 
linked to the colorspace web page and manuscript - both of which have much 
more references.

Best,
Z
