Converts your rr stack into an html+css documents, within a framing system for
easy navigation from one card to another. (Note that you may need to use ctl+
or ctl- to adjust the font size on your browser). Early draft to evaluate the

Color Wheel
-----------
Presents a color wheel to easily select colors that are complementary, in
tetradic or quadratic harmony, with varying levels of brightness and saturation
(check out the wiki page on computers in education/design for information on
this). Converts RGB into the corresponding HTML color code (i.e., #000000).
