Translation of the twitter-text-* processing libraries to Objective-C for use on iOS.
There's probably a lot of very naïve code in here: writing this, I was reminded how little I like doing intensive string processing in Objective-C/Cocoa. Performance patches welcome. :-)
I've also incorporated the excellent RegExKitLite. I am using the block-based methods introduced in version 4, so this code does require iOS 4+.
