CUHF as a reference

[susilehtola]

It looks like many parts of the code don't work with reference CUHF. I am wondering whether this should be the case. Shouldn't CUHF work in whatever code already has the ROHF reference implemented?

If there are no ROHF-specific formulas, sure. But if a module has specific methods and formulae for ROHF, I think those need to be checked for CUHF compatibility on a case-by-case basis.
