class DirectionalLight from Vrml 

	---Purpose:defines a directional  light node of VRML specifying
	--         properties of lights. 
    	--  This  node  defines  a  directional  light  source  that  illuminates   
    	--  along  rays  parallel  to  a  given  3-dimentional  vector
    	--  Color is  written  as  an  RGB  triple.
    	--  Light intensity must be in the range 0.0 to 1.0, inclusive.
