I don't understand the multicol solution for the 'sushi' flow. I'm
interpreting the layout intent as:

1. Start the sushi flow in a single region on page 1
2. Continue the sushi flow after all of the main article text is finished

The second (and possibly subsequent) regions for the sushi flow do not
necessarily land on page 3. Which page the sushi flow continues on depends
on how the main article text lays out. How this works is what we need to
define in some sort of 'page masters' module.

Thanks,

Alan
