Extend DOM to handle hOCR

• hocr-dom
• hocr-dom-jsdom

The main package, contains code for querying hOCR elements and parsing / accesing properties.

See the README for API docs.

In short, in the browser, you will only need

HocrDOM.extendPrototypes(window)

After this, you can use document.queryHocrAll on document and elements, as well as access properties via their hocr property.

Contains a browser-independent HTML parser with built-in hOCR support, thanks to jsdom.
