 /**
 24   
  * An implementation of {@link org.apache.hivemind.ServiceImplementationFactory}that looks for a
 25   
  * service implementation provided as an
 26   
  * {@link org.apache.tapestry.spec.ILibrarySpecification#getExtension(String) application
 27   
  * extension}. If no such extension exists, then a
 28   
  * {@link org.apache.hivemind.lib.DefaultImplementationBuilder default implementation}is
 29   
  * constructed and returned instead. This allows compatibility with Tapestry 3.0 and earlier
 30   
  * application extensions (though those will be phased out in the future).
