Methods Summary

`R_A`(self)	Obtains (R^t)^-1 for monomer A.
`R_B`(self)	Obtains (R^t)^-1 for monomer B.
`aux_overlap`(self)	Obtains the FDDS aux_overlap.
`form_aux_matrices`(self, arg0, arg1)	Forms the uncoupled amplitudes and other matrices for either monomer.
`form_unc_amplitude`(self, arg0, arg1)	Forms the uncoupled amplitudes for either monomer.
`get_tensor_pqQ`(self, arg0, arg1)	Debug only: fetches 3-index intermediate from disk and return as matrix.
`metric`(self)	Obtains the FDDS metric.
`metric_inv`(self)	Obtains the FDDS metric_inv.
`print_tensor_pqQ`(self, arg0, arg1, arg2)	Debug only: prints formatted 3-index intermediate to file.
`project_densities`(self, arg0)	Projects a density from the primary AO to auxiliary AO space.
