-----------------------------+-----------------------------------------
We currently compute the charge of a rigged configuration `R` by taking
the maximum cocharge over the entire set of rigged configurations and then
subtracting `R.cocharge()`. Cocharge is constant on classical components,
so it is sufficient to check this on classically highest weight elements
(which are generated and stored in the `module_generators` attribute).
