Instead of diagonalizing the hamiltonian, perform CPF calculation (ncpf=2)
(not yet implemented) ACPF calculation (ncpf=0) or
AQCC calculation (ncpf=1). For ACPF and AQCC, the internal
and external normalization factors gacpfi, gacpfe may be reset from
their default values of 1, 2/nelec and
1, 1-(nelec-2)(nelec-3)/nelec(nelec-1),
respectively.
