Description

A triangle is comprised of three edges. They are ordered clockwise one after another. So, the RightTriangle of an edge is the triangle the edge belongs to. An edge's neighboring edge is the edge of the LeftTriangle that shares the same nodes (although from and to are reversed).

GetNeighbor will return Nothing (a null pointer) when the edge is on the absolute boundary of the triangulation.
