Code for creating epub files.

'epub.py' may be of general use.

The project as a whole is currently oriented towards converting creating .epub files from Internet Archive book 'items', consisting of metadata, 'abbyy' OCR output files, and page images.

Entry points -

• convert_iabook.py - main Internet Archive book converter
• condense_abbyy.py - create slightly-more-human-readable version of abbyy
• visualize_abbyy.py - create a directory of page images, marked with OCR (Needs currently un-checked-in fonts)
