New description:
This patch is an attempt to implement new bases of NCSF and QSym which
currently exist on the combinat server. This includes the Monomial basis
and Fundamental basis of Tevlin, the dual of the quasisymmetric Schur
function introduced by Haglund, Luoto, Mason and van-Willigenburg, the
Immaculate basis, introduced by Berg, Bergeron, Saliola, Serrano and
Zabrocki. In QSym, it will implement all of the dual bases of NCSF.
Currently the attached patch implements only the Quasisymmetric Schur
functions of Haglund, Luoto, Mason, and van-Willigenburg, plus some
combinatorics of Composition Tableaux

Comment:
Hey Jeff,
I've uploaded a review patch which moves the composition tableaux into its
own file and does some minor cleanup of the docstrings and removing
whitespace. There is a trivial dependency on #14101 in the
`combinat/all.py`. If you're happy with my changes, go ahead and set this
to positive review.
Best,[[BR]]
Travis
