NSAttributedString+DDHTML

Simplifies working with attributed strings by allowing you to use HTML to describe formatting behaviors.

NSAttributedString+DDHTML isn't intended to support full HTML rendering. Instead it provides a quick, effient and light-weight implementation for leveraging attributed strings when utilizing native UIKit interface elements.
