sltcnd_excit Interface

public interface sltcnd_excit

@brief Evaluate Matrix Element for different excitations using the Slater-Condon rules.

@details This generic function uses compile time dispatch. This means that exc cannot be just of class(Excitation_t) but has to be a proper non-polymorphic type. For run time dispatch use dyn_sltcnd_excit.

@param[in] exc, An excitation of a subtype of Excitation_t.
