Overview

   This factory is used to split a double-sided surface geometry to two separate 
   single-sided surface geometries, one facing forward, and one facing backward, 
   which are output through the FRONT and BACK ports respectively. 

   This factory accepts all features; however, only features containing surface 
   geometries will be processed, and all other features are output through the 
   INVALID port. 

Output Tags

   The SurfaceSplitterFactory supports the following output tags.
   
   FRONT 
   
      Feature containing a surface representing the front side of the original 
      surface.
   
   BACK  
   
      Feature containing a surface representing the front side of the original 
      surface.
   
   INVALID  
   
      Features that do not contain surface geometry are output, unchanged.
