Checking for empty chunks in the layout is not very handy because
there's too much code in layout.
Too much code in layout = harder migration/implementation on new
layouts
I'm trying to do those checks before the layout rendering
so the only code in layouts will be
<?php $something_for_layout ?>
What about checking Chunks in AppController's beforeFilter() ?
