This removes the page/note dichotomy, since it wasn't working
as well as I'd hoped. The discipline required now is higher
where the data store layer is concerned, but the actual structures
are smaller and more efficient.
Well, as complete as it could be without proper automated testing.
I think there'll be some more testing soon, as it doesn't make sense
for it to hang out so blatantly like this.
Both a fmt and clippy pass have shaken all the lint off, and right
now it builds without warnings or lintings. Wheee!
