New description:
Trac # 8911: Use category framework for crystal code
(depends on #8881)
New crystal categories:
- crystals
- finite_crystals
- highest_weight_crystals
- classical_crystals
together with a template in
categories/example/crystals
on how to implement a new crystal.
The files
combinat/crystals/letters.py and
combinat/crystals/tensor_product.py
combinat/crystals/spins.py
combinat/crystals/fast_crystals.py
combinat/crystals/highest_weight_crystals.py
combinat/crystals/direct_sum.py
combinat/crystals/affine.py
combinat/crystals/kirillov_reshetikhin.py
have been categorified. What was before in
combinat/crystals
is now mostly in the various categories except for the BackTracker class
and the documentation about crystals.
