New description:
Enhancement to the cluster_algebra_quiver package: User can define a
cluster algebra seed by entering a cluster triangulation class T of a
surface. User can then compute the T-expansion of an arc or loop gamma by
entering the arcs of T that gamma crosses.
The algorithm used is the perfect matching formula from the following
papers:
"Positivity for cluster algebras from surfaces"
http://arxiv.org/abs/0906.0748 (section 4).
"Bases for cluster algebras from surfaces" http://arxiv.org/abs/1110.4364
(section 3).

Comment:
When I run "./sage -docbuild reference/combinat html" I get errors and I
have not been able to figure out how to fix them.
When pushing to trac, I did "git push --set-upstream trac
HEAD:u/egunawan/ticket/16310". Was this the correct command?
