New description:
So we can do things like this:
{{{
sage: K = KirillovReshetikhinCrystal(['D',4,1], 2,1)
sage: K[4].pp()
1
4
sage: K[12].pp()
-3
-1
sage: T = TensorProductOfCrystals(K, K)
sage: T[22].pp()
(X) 2
-3
sage: T[50].pp()
1 (X) 1
2 -3
sage: pm =
sage.combinat.crystals.kirillov_reshetikhin.PMDiagram([[1,0],[0,1],[2,0],[0,0],[0]])
sage: pm.pp()
. . . +
. . - -

sage: K = KirillovReshetikhinCrystal(['B',3,1], 3,3)
sage: K.module_generators[0].pp()
+ (X) 1

}}}
