  /**
   * \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
