New methods in HedgeGraph allowing to snap multiple d3+ vertices together and to update edges topology accordingly. Note : It is a quick fix as i do not have time to handle all the possible cases. I think of two possible break cases that could happens and are not handled : Limit 1 : A vertex can't be snapped multiple times (i.e when 2 holes ar enext to each other it'll break). Unknwon behavior in this case Limit 2 : New edges could step outside polygons boundary in case of extremely narrow polygons. Error will be known later when, for example, using constrained simplification or length computation.
