Block Page (with Layout plugin)

This is a copy of the 'block_page_layout' example module that used to live in Layout Plugin.

This example module was never intended to be used in production - if you want to integrate Layout Plugin with Page Manager, then use Panels! However, a few people have unfortunately used it in production, so rather than just removing it from Layout Plugin, we've moved it here.

If anyone is interested in maintaining this module and taking it out of 'example' status, than please create an issue requesting ownership!
