class NormalBinding from Vrml 

	---Purpose: defines a NormalBinding node of VRML specifying properties of geometry
	---          and its appearance.
    	--  This node specifies how the current normals are bound to shapes that follow in the scene
       	--  graph. Each shape node may interpret bindings differently. 
    	--  The bindings for faces and vertices are meaningful only for shapes that are made from
       	--  faces and vertices. Similarly, the indexed bindings are only used by the shapes that allow
       	--  indexing. For bindings that require multiple normals, be sure to have at least as many
       	--  normals defined as are necessary; otherwise, errors will occur.
