Description
I split TensorProductOfCrystals? into TensorProductOfCrystalsWithGenerators? and FullTensorProductOfCrystals? (with or without the option of being a classical crystal). This makes it possible to have a more efficient way to access list, count, etc for tensor products that do not have module generators.
Also, the distinction between the specifications of module_generators and highest_weight_vectors is made more precise (which made it necessary to slightly change the implementation of Daniel Bump on characters).
This change is necessary for the upcoming implementation of affine crystals.
