AO Restricted Fock Op

Restricted Fock Operator Builder

This module builds the Fock operator given a restricted density. Under this assumption, the Fock operator is created by mapping each term in the electronic Hamiltonian to itself with the exception of the electron-electron repulsion. The electron-electron repulsion is mapped to 2J-K where J is the Coulomb operator for the electrons interacting with a density and K is the exchange operator for the same density.

N.b. Empty densities are treated as zero densities and this module will skip adding 2J-K if provided an empty density.
