Most of these changes are fine. We can probably get rid of the main layout-container. That came with the template from Classy, but if it isn't needed we can remove it.

I talked to Adrian about this and we agree that we could get rid of the 'if' but it might be good to leave it as an example.

This looks fine. There are a couple things I'd like to do different, but we can follow up with that. Right now I want to get the regions in so we can work on the CSS.

Also, @adoo, I'm not too found of these 'if's for adding classes.

...but we can leave them for now. One thing I don't like is that this leaves a lot of extra white space in the class attribute. You can see it in the page source. I added dashes in the if to remove the extra whitespace. You can see that after it is committed.

I also updated to comment block with the new regions.
