Privacy View Factor

I have finished the privacy evaluation node - I have called it Privacy View Factor. It calculates a privacy measure for each window. Privacy is affected only by overlooking from other windows. So it does not take into account people on the ground or the street, so I guess it is best for highrise.

The way it does this is that, for each window, it finds the worst neighbour - i.e. the one overlooking you the most. The worst neighbour is calculated based on the distance and the angles of the windows. The value is then converted to a percentage - 100% means complete privacy, while 0% means no privacy.
