Old description:
> The upcoming patch will implement the Kirillov-Reshetikhin crystals for
> nonexceptional types that are currently still missing.
New description:
This patch adds the following new features for crystals:
- CrystalOfTableaux now also accepts half-integer shapes for spin tableaux
for type B_n and D_n
- New alternative implementation of KR crystals of type A_{2n}^{(2)} by
using the B_n classical decomposition
- Implementation of KR crystals B^{n,s} of types B_n^{(1)}, C_n^{(1)},
D_{n+1}^{(2)}
