Description
The method outerNormal of the UGGrid LeafIntersectionIterator does not give the correct result when the grid is nonconforming and the intersection is a nonplanar quadrilateral. Reason: the input coordinates are interpreted with respect to the element face and not with respect to the intersection. This doesn't matter if the intersection is conforming or if the normal is constant anyways. But for nonplanar faces there needs to be a coordinate transformation.
Assigning to me.
