Old description:
> See: http://wiki.sagemath.org/combinat/MultivariatePolynomials
New description:
We build an implantation of polynomials as formal sum of exponents. This
allows to work on any number of variables with some easy morphism. We use
some actions of Weyl group on the exponents to create operators
(especially divided difference operators).
These operators allow us to build different bases that comes from geometry
and have nice combinatorial description.
