* Source code for the determinant part
Storage of the determinants is a particular case,
which requires special treatment, but has to be coded only once
Storage of the determinants is a particular case,
which requires special treatment, but has to be coded only once
(since there is only one group that corresponds to it).
Thus, there is no need to auto-generate this part via templates.

This section concerns API calls related to Slater determinants.
