class Separator from Vrml 

	---Purpose:  defines a Separator node of VRML specifying group properties.
    	--  This group node performs a push (save) of the traversal state before traversing its children
       	--  and a pop (restore) after traversing them. This isolates the separator's children from the
       	--  rest of the scene graph. A separator can include lights, cameras, coordinates, normals,
       	--  bindings, and all other properties. 
       	--  Separators can also perform render culling. Render culling skips over traversal of the
       	--  separator's children if they are not going to be rendered, based on the comparison of the
       	--  separator's bounding box with the current view volume. Culling is controlled by the
       	--  renderCulling field. These are set to AUTO by default, allowing the implementation to
       	--  decide whether or not to cull.
