Class Fresnel

Function for computing the Fresnel reflectivity for a single interface.

rho,Vrho: scattering length density of substrate and vacuum
mu,Vmu: absorption of substrate and vacuum (note that we do not correct for attenuation of the beam through the incident medium since we do not know the path length).
sigma (angstrom): interfacial roughness
