Comment (by kdilks):
{{{minimal_schnyder_wood}}} relies very heavily on the input being in the
same form as the output of {{{graphs.Random_Triangulation}}}. If this were
purely a helper function for computing random Tamari intervals, that would
be fine. But as something defined on all graphs, I think there should be
some kind of check to make sure the input is a planar triangulation, and
the user should be able to specify what they want the root edge to be.
Also, the purpose of the optional parameter {{{minimum=False}}} isn't
documented.
Still need to look at the two papers to understand the code/algorithms,
but the end product seems to work.
