Is there a way to avoid \ style I find it jarring and inconsistent.

This is a much better naming scheme. Dir structure should be a clear, consistent way to traverse the source.

... I'm not clear what you're talking about? Do you mean the \Ohanzee\Database type references? The \ prefix is necessary because we're in a namespace. The alternative is to insist on use statements instead... I can definitely do that, it just requirement more than find and replace.

Updated to remove \Ohanzee\DB and use Ohanzee\DB instead.

LGTM except the tests, I think that's just linting
