I think that it s certainly a mistake to call the "real" class `C_prime`
and then proceed to use the shortened name `Cp` throughout the code.
It shouldn't matter which one is the real class and which one is an alias.
If it does, then that should be a bug with `BindableClass`. I'm fine with
making `Cp` the "real" name, but I'd like at least `C_prime` to available
since that is a natural python name (and perhaps deleting
`kazhdan_lusztig` since it's ambiguous being the C and C' bases?).
I have no preference on the sign and the string representation. Just for
the record, you can input `C[s1*s2*s1]`.
