Exporting works, about to start AngularJS browser

Running index.js will convert the XML file into JSON files stored in the
source dir of the docs dir.

I still need to adapt the index.js code to be more flexible, output for
vim/phpstorm, and have decent command line options.

This is just a start.
Basic documentation system is now working.

Added bootstrap to make it pretty. Tweaked some of the JSON objects
before writing them to disk. Made an AngularJS app to view the
documentation system. Filtering works perfectly. Can click types to view
docs about them. Function signatures, stuff like that.
