Add weight property to point in case of circle

[NSMutableString]

I am using uMap to make an overview of a small forest area. I'm using a point as type circle for the most important trees. At this moment, each circle has the same size, a quick overview on the map does not show the difference if a tree is big or not. That's were the weight property would come in handy. Not sure that something like that is easily possible. You would end up with smaller and bigger coloured circles on the map. Or in case something similar could be achieved in another way, I'm happy to hear.

Thanks a lot for the splendid map service.
