class WWWAnchor from Vrml 

	---Purpose: defines a WWWAnchor node of VRML specifying group properties.
    	--  The  WWWAnchor  group  node  loads  a  new  scene  into  a  VRML  browser 
	--  when  one  of  its  children  is  closen.  Exactly  how  a  user  "chooses" 
	--  a  child  of  the  WWWAnchor  is  up  to  the  VRML browser. 
	--  WWWAnchor  with  an  empty  ("")  name  does  nothing  when  its   
	--  children  are  chosen. 
	--  WWWAnchor  behaves  like  a  Separator,  pushing  the  traversal  state 
	--  before  traversing  its  children  and  popping  it  afterwards.
