 * \brief Create standardised Option structure.
 *
 * This function will create a standardised Option structure defined
 * by parameter opt. A list of valid parameters can be found in gis.h.
 * It allocates memory for the Option structure and returns a pointer
 * to this memory.
 *
 * If an invalid parameter was specified a empty Option structure will
 * be returned (not NULL).
