Bidi class optimization

[edkimmel]

bidi_class_for as it stands now is very slow. A linear search and the multiple parseInt calls per character are to blame.

I ended up fixing the generated file directly for my own application. I've created a pull request with that file to show the changes that would ultimately have to happen when generating the javascript files.

The bidi_classes object is now a sorted array of ranges, and the bidi_class_for method performs a binary search to find the correct range.

Thanks for figuring this one out, @edkimmel!

As you noted yourself, this file is in fact generated. The original CoffeeScript code can be found over here with the data generated in Ruby over here. Do you think you could apply your changes to the original implementation so we can regenerate all JS files from it?

Thanks, yes, the file is generated. @KL-7 Thanks for CoffeeScript code.
