Args
`operator`	Dual-basis representation of FermionOperator to evaluate expectation value of. Can have at most 3-body terms.
`plane_wave_occ_orbitals`	`list` list of occupied plane-wave orbitals.
`n_spatial_orbitals`	`int` Number of spatial orbitals.
`grid`	`openfermion.utils.Grid` The grid used for discretization.
`spinless`	`bool` Whether the system is spinless.

Returns
A real float giving the expectation value.
