A model for leaf fluorescence, reflectance and transmittance spectra. It implements
the model introduced by Vilfan et al. (2016) <10.1016>. Fluspect-B
calculates the emission of ChlF on both the illuminated and shaded side of the leaf.
Other input parameters are chlorophyll and carotenoid concentrations, leaf water, dry matter
and senescent material (brown pigments) content, leaf mesophyll structure parameter and ChlF
quantum efficiency for the two photosystems, PS-I and PS-II.10.1016>
