New description:
Existing code for nonsymmetric Macdonald polynomials in Sage (#2708) is in
ns_macdonald.py.
It uses the HHL algorithm and is limited to Type A. The patch at hand
extends this to arbitrary
Cartan types using Demazure-Lusztig operators.
The patch was written with substantial input from Daniel Orr, Daniel Bump,
Mark Shimozono, Bogdan Ion and Siddhartha Sahi.
The patch in the combinat queue is trac_14102-nonsymmetric-
macdonald.patch.
