Adding changes to the real space modeling that allow calculation of the USANS (slit-smeared) intensity from an anisotropic structure that has been generated using a real-space construction. The detector plane from the FFT result is converted to USANS, on absolute scale. Will be extended as it gets some use, but it is functional and is found from the "3D Examples" Macros submenu. Documentation is on the way too.
