I haven't actually wrote a solution for this yet. I've just had a brief look at it. The principle behind it doesn't look too difficult, so I shouldn't imagine it would present too many problems. I'll complete it soon and share my solution. If you also want to do it, feel free! If you have any questions/experience any difficulty, please don't hesitate to ask questions.
