Description (last modified by Eric Marberg)

Currently crystals.ShiftedPrimedTableaux? implements a gl(n)-crystal structure on shifted primed tableaux. The goal of this ticket is to upgrade this to a slightly more general q(n)-crystal structure. This involves implementing one additional set of "queer" crystal operators.

The merging on trac is less forgiving than on our computers. Trivial rebase.

Too late, but this :

if len(two_primes) == 0:

could have been simplified to

if not two_primes:

which is faster.
