New Features:
Changes:
Removed the dependence on the 'rgl' pacakge, since some people have trouble installing the external dependency (XQuartz) on Macintosh computers. Replaced it with 'scatterplot3D' for our 3D plots.
Added a 'getLUV" function so people who still want to use 'rgl' can more easily do so.
New Features:
Added a new function, 'colorDeficit', that converts any palette to the equivalent that would be seen with a specifric form of color deficit vision.
Added two new precomputed palettes, Light24 and Dark24.

Changes:
Added a second vignettte, focused on creating palettes.
Removed the 'turnGray' function, since it duplicates functionality from colorspace::desaturate.
Added error checking to the arguments of most of the functions.
Changed 'swatch' so it uses the luminance to decide whether to write color labels in white or black.
Changed the 'computeDistances' function so it includes the default starting point, thus obviating the need for adding one when you count the number of separated colors. (Technically, the distance for the first point should be infinite, but we set it to the distance to the second point to make it easier to plot.)
Changed the 'plotDistances' function so it now colors the points.
