jonnyt: i wanted to convert this from a multi as the place the final point is in is now subject to muggling and not as nice as it was, i also appreciate that people dont like multis as much. It was first placed as such to avoid a nano but as i have put more out now which arent nanos i feelless guilty :-).
Mark II will be published but it will be in the same place as the first stage of the previous one.
