       This is a subclass of SoSeparator that redraws itself in a different color when the cursor
       is over the contents of the separator.

       The  redraw  happens  for  that separator only and not the entire window (redraw along the
       handle event pick path) and in the front buffer, to efficiently track  the  mouse  motion.
       The  highlighted  redraw overrides the emissive and/or diffuse color of the subgraph based
       on the field values in this node.

       NOTE: when using SoLightModel::BASE_COLOR (to turn lighting off) only  the  diffuse  color
       will be used to render objects, so EMISSIVE_DIFFUSE must be used for this node to have any


     SoSFColor           color
          highlighting color - default [.3, .3, .3]

     SoSFEnum            style
          highlighting draw style - default EMISSIVE

     SoSFEnum            mode
          Whether to highlight or not - default AUTO


          Creates a LocateHighlight node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.


          Checks to see if the cursor moves onto or off of the contents  of  the  separator,  and
          redraws appropriately (if mode is AUTO), otherwise traverses as a normal separator.

          Redraws  either  highlighted (if cursor is over the contents of the separator when mode
          == AUTO or always if mode == ON), otherwise traverses as a normal separator.
