New description:
Implement edge-by-edge options for latexing graphs with dot2tex
Here we color in red all edges touching the vertex ``0``::
{{{
sage: G = graphs.PetersenGraph()
sage: G.set_latex_options(format="dot2tex", edge_options = lambda
(u,v,label): { "color": "red" if u==0 else 1})
sage: view(G)
}}}
By the way, this refactors the code of color_by_label to simplify its
logic and generalize it for dot2tex output.
It also fixes a couple typos in the documentation, as well as
little shortcomings in the quotation functions in dot2tex_utils.
Patch also available from the Sage-Combinat queue:
