/*! @brief Semi-transparent radiation problem. Pb_rayo_semi_transp is a Probleme_base with 4 specific features:
 *
 *   * Its equation must be typed according to the discretisation.
 *     This requires deferring certain initialisations until the discretisation is known.
 *   * It shares its domain with a hydraulic-type problem.
 *   * There is only one time value (future = present).
 *     It should ideally be made time-independent.
 *   * It holds a reference to the hydraulic problem, used extensively.
