Description (last modified by )
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.
New commits:
implemented queer lowering operator and tests
implemented queer raising operator and tests
change from 0index to 1index
added Assaf and Oguz reference
