Basic surface-surface intersection description. Constructed from two surfaces it creates a description of the intersection. The intersection information consists of the intersection line(s) with new points, new edges between points (note that these edges and points are on both surfaces) and various addressing from original surface faces/edges to intersection and vice versa. Gets either precalculated intersection information or calculates it itself. Algorithm works by intersecting all edges of one surface with the other surface and storing a reference from both faces (one on surface1, one on surface 2) to the vertex. If the reference re-occurs we have the second hit of both faces and an edge is created between the retrieved vertex and the new one. Note: when doing intersecting itself uses intersection::planarTol() as a fraction of current edge length to determine if intersection is a point-touching one instead of an edge-piercing action.
