<DD>If the Layout has not been defined by the Screen then set the
 layout to be "DefaultLayout".  The Screen object can also
 override this method to provide intelligent determination of
 the Layout to execute.  You can also define that logic here as
 well if you want it to apply on a global scale.  For example,
 if you wanted to allow someone to define Layout "preferences"
 where they could dynamicially change the Layout for the entire
 site.  The information for the request is passed in with the
 RunData object.<DD><DL>
