Starting a major overhaul - NO COMMITS

[jordansparks]

We're finally building our middle tier properly. But it's a massive rewrite process. During this process, there could be extensive periods during which the head will not compile. Nobody else should be making commits but us for at least a few weeks. We'll let you know when it's safe again.

The overhaul is done. Back to normal now.
