Models of the grating multilayer coatings.

Functions

multilayer_design()	The as-designed multilayer coating for the ESIS diffraction gratings.
multilayer_fit()	A multilayer coating determined by modifying multilayer_witness_fit() to have a glass substrate with the appropriate roughness.
multilayer_witness_fit()	A multilayer stack fitted to the witness sample measurements given by multilayer_witness_measured().
multilayer_witness_measured()	A reflectivity measurement of the witness samples associated with the ESIS diffraction gratings gathered by Eric Gullikson.
