Framework update

I've finally resolved the problems with certificate signing - turned out to be a ID ten T error - and so can finally get on with more important stuff.

I've also done a lot of documentation (while I was stuck on that signing bug), although in places it's a bit sparse. Not everything is documented yet, but I'm working on it.

That's about all, really. I've been working through my midyear exams the last two weeks (4 down, 5 to go), which is why this update has been so long coming. Expect much better things in the next month.
