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`
* Spin crystals have a new method _repr_ using the signature
representation and a new latex method
* 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)}`
