Comment (by jhpalmieri):
For the link for Kuen's surface in `parametric_plot3d`, there are lots of
choices, for example http://virtualmathmuseum.org/Surface/kuen/kuen.html
(or http://mathworld.wolfram.com/KuenSurface.html, if we want to link to
Wolfram ;).
I think that the link for `graphs/generators/basic` should be
http://www.orgnet.com/sna.html.
I don't know what to do about the link in `implicit_plot3d`, maybe just
delete it altogether:

Unfortunately, I can't figure out who to credit for the plot, except that
it might have been someone named "Summers"...
