Reenabling the Dwelling Processor Registrar to load files
Made neighbour finding algorithm take no heed of priority. I.e. now it will pick up both a borough and polling district boundary
Fixed a bug with this which lead to only the edge rather than the edge squared distance being compared to the distance squared from the point being checked.
Added a check for when the Rectangles do not intersect
Added code to handle the fact that it was now expected to be a common occurence that a point would be added which had multiple neighbours
Minor tweek to ensure that if a big dot is drawn then the mouse will be stuck on the boundary from the point of view of the Constructor at least by making it sticky at twice the radius of the big dot
