Final Version

The final version of the book is now online. I've fixed a lot of mistakes in the last couple of weeks and I've written a proper introductory chapter. I've managed to decrease the size of the file a little too. The book has now been submitted to the publisher, but please mail me if you find any errata - I'm sure there are still loads. I can still correct things when I get the proofs (around December, apparently).

Final edits

Loads of tiny changes since last time, but nothing significant. Just trying to work out the remaining kinks now and don't expect to be adding any more content except for a short introduction. If you find any problems, please mail me about them ASAP before the book goes off to the publishers!
