/**
 * \class LabelToProSailParameters
 * \brief Take a label corresponding to a spectrum type for vegetation and outputs the ProSail parameters needed to get a spectrum of that type.
 *
 * Output parameters concerns:
 *  - Step1: parameters for PROSPECT simulation.
 *  - Step2: parameters for SAIL simulation (see http://teledetection.ipgp.jussieu.fr/prosail/).
 *
 * WARNING: an only set of parameters is defined for all vegetation types.
 *
 * Prospect Parameters
 * Cab    = 30;   % chlorophyll content (ug.cm-2)
 *  Car   = 10;   % carotenoid content (ug.cm-2)
 * Cbrown  = 0.0;  % brown pigment content (arbitrary units)
 * Cw    = 0.015;  % EWT (cm)
 * Cm    = 0.009;  % LMA (g.cm-2)
 * N   = 1.2;  % structure coefficient
 *
 * Sail Parameters
 * lai   = 2;    % leaf area index
 * angl  = 50;   % average leaf angle (deg)
 * psoil = 1;    % soil coefficient
 * skyl  = 70;   % % diffuse/direct radiation
 * hspot = 0.2;  % hot spot
 * ihot  = 1.0;  %
 * tts   = 30;   % solar zenith angle (deg)
 * tto   = 0;    % observer zenith angle (deg)
 * psi   = 0;    % azimuth (deg)
 *
 *
 * TODO : define different vegetation types and ProSail parameters associated.
