-----------------------------+------------------------------------------
One of the TODOs that remains in the documentation for ncsf_qsym is to
implement a short list of bases from the literature. One of those bases
is the dual basis to the quasi-Schur basis of QSym. We should be able to
use the transition coefficients that are implemented in qsym.py to compute
the dual quasi-Schur basis. This may mean factoring out the methods from
qsym.py to combinatorics.py or perhaps just accessing those methods where
they are.
