CISD
====
This is a test directory which builds a CISD by setting the follwoing rules:
* The only generator determinant is the Hartee-Fock (single-reference method)
* All generated determinants are included in the wave function (no perturbative
selection)
These rules are set in the ``H_apply.irp.f`` file.
Needed Modules

`cisd <http://github.com/LCPQ/quantum_package/tree/master/src/CISD/cisd_lapack.irp.f#L1>`_
Undocumented
`h_apply_cisd <http://github.com/LCPQ/quantum_package/tree/master/src/CISD/H_apply.irp.f_shell_8#L406>`_
Calls H_apply on the HF determinant and selects all connected single and double
excitations (of the same symmetry). Auto-generated by the ``generate_h_apply`` script.
`h_apply_cisd_diexc <http://github.com/LCPQ/quantum_package/tree/master/src/CISD/H_apply.irp.f_shell_8#L1>`_
Generate all double excitations of key_in using the bit masks of holes and
particles.
Assume N_int is already provided.
`h_apply_cisd_monoexc <http://github.com/LCPQ/quantum_package/tree/master/src/CISD/H_apply.irp.f_shell_8#L263>`_
Generate all single excitations of key_in using the bit masks of holes and
particles.
Assume N_int is already provided.
