EPUB3 - useful tool

Hi, this pull request is more to let you know about a tool I'm working on called Hatter. You start with a plain text file, mark sections and add some html and it will generate an epub3 version of the book. I used the latest dev version (what will be v1.0.2) of Hatter to generate the open_access_ebooks.epub file at the root of this repository. You can learn a bit more about Hatter here: http://bald-mountain.blogspot.com/2013/02/hatter-app-to-turn-text-files-into-epub.html and get Hatter on the Apple App store here: https://itunes.apple.com/us/app/hatter/id599454393?mt=12 I'm a little embarrassed to admit that version 1.0.0 is a bit busted. Version 1.0.1 is in review and fixes a bunch of problems. Version 1.0.2 will come soon after. I've been working with a small publisher in Taiwan to fix some issues related to generating Chinese books.

I think this application will make generating open books a lot easier. The best part is, the app is only $10, which puts it in reach for just about anyone.
