Create an S2D.RIDefinition object from the GladstoneDale equation.
Args:
mediaRI: The refractive index of the media that the chromatin is immersed in.
CVC: The CVC, also referred to as Phi. The ratio of Chromatin Volume : Total Volume, kind of like density.

Create a system configuration object. This object contains all information about the microscope and sample refractive indices.
Args:
ri_def: An RI definition object
na_i: The illumination NA of the objective.
na_c: The collection NA of the objective.
center_lambda: The center wavelength of illumination. This should be the center in K-space. So, the wavelength of the center wavenumber.
oil_immersion: If True then the objective is treated as though it is immersed in RI_glass. If False it is treated as though it is immersed in RI_media.
cell_glass_interface: If True then the cell/glass interface is treated as the reference reflection of the configuration. If False then the cell/media interface is treated as the reference reflection.
