Adjacent areas

[davalv@…]

I propose a new functionality.

Suppose that we have 2 overlapping areas (partially or totally), for example landuse=residential the first and landuse=forest the second.
Suppose that I have created a very large residential area and then I want to insert within a forest area.
I am lazy, I don't want to change the residential area. So i draw the forest area on it.
But it is not correct. I should draw them so that they are not overlapping.

So I select the residential area, then the forest area and press a "magic button": the border of the residential area that was affected by the overlap now shares the same nodes of the forest one.

Steps of the new functionality:

• identify which parts of the residential perimeter intersect forest area and deletes them
  
• connect each orphan residential node to the nearest one of forest perimeter
  
• recreate the missing residential perimeter following the forest perimeter and using the same nodes
