---------------------------+------------------------------------------------
This patch includes algorithms for the Bruhat order, Kazhdan-Lusztig
polynomials, improvements to the {{{__repr__}}} method of WeylGroup
elements, and other enhancements.
Some of the methods should be moved to {{{coxeter_group.py}}}.
Mike Hansen is working on an interface to coxeter3, which is be able to
compute Kazhdan-Lusztig polynomials rather faster. However I think this
patch still contains things that are needed.
