code: public static UIResults getGeneric(HttpServletRequest httpRequest) {
  		UIResults results = (UIResults) httpRequest.getAttribute(FERRET_NAME);
  		if (results == null) {
  			results = new UIResults(httpRequest);
  		}
  		return results;
  	}
docs: Extract a generic UIResults from the HttpServletRequest. Probably used
  by a header/footer template .jsp file.
  @param httpRequest the HttpServletRequest where the UIResults was
  ferreted away
  @return generic UIResult with info from httpRequest applied.
