 public boolean requiresLayout()
Configurators call this method to determine if the appender
requires a layout. If this method returns true,
meaning that layout is required, then the configurator will
configure an layout using the configuration information at its
disposal. If this method returns false, meaning that
a layout is not required, then layout configuration will be
skipped even if there is available layout configuration
information at the disposal of the configurator..

In the rather exceptional case, where the appender
implementation admits a layout but can also work without it, then
the appender should return true.

 public  void setLayout(Layout layout)
