So, that's an artifact of an unfinished adventure. Here I was thinking about checking for the presence of Octopress Ink and grabbing plugin layouts from that to see if post or page layouts were set by a theme or plugin. Then I'd automatically default to the `theme:post` or `theme:page` if it is available. I should probably just let them set the default layout in the config file. It would certainly be a lot easier to code.
