Spectral Rendering Part II - UV Lighting and Fluorescence

My latest feature for FancyRay was the introduction of Fluorescent materials.  Fluorescent materials work by first absorbing the incoming frequencies of light at varying degrees based on its unique wavelength absorption function, and then modulates the absorbed frequencies by a predetermined mapping function from absorbed -> emitted. This mapping function, shifts the wavelengths towards higher values and modulates their intensities.
