Comment(by jbandlow):
Recording todo's for myself here:
1. Doc and tests throughout
2. The partial morphism from qsym --> sym is implemented with
.to_symmetric_function(). The reverse morphism should be implemented in
SF.
3. Look at how principle specializations are implemented in SF, and be
implement here in a consistent way.
4. Homomorphisms to/from polynomial rings should also be implemented.
5. The combinatorial rule for multiplying fundamentals is not implemented,
and should be.
