Detailed Description

Computes components of the Fock matrix necessary for closed-shell calculations (i.e.

CLSCF). Requires as input the total AO density matrix P(0). Output matrices are in AO basis. If f_b1 == f_b2 then the output is the skeleton AO matrix that needs to be symmetrized with PetiteList, else the output is the full AO matrix.
