I was playing around with Madge and noticed that the previous dependency
graph looked almost *exactly* like a bowl of spaghetti I had last week.
After a few hours on Wikipedia I got interested in refactoring the code
so that each `require()` imported a module from one level deeper into
the tree.
I don't know if this is actually useful, but it's better than spaghetti.
In the future I think I should probably refactor the database
convenience functions out of the "models" since they really aren't
models but it's the best name I could come up with for what they are and
how they're used. This will probably go through some more evolution when
I rip out EJS and replace it with something much smaller.
