TSplineEdge
The TSplineFaces adjacent to this Edge
            
The Vertex at which this Edge ends
            
Index of the TSEdge
            
Whether the TSEdge is on border
            
Whether the TSEdge is manifold
            
The TSplineVertex at which this Edge starts
            
Return UVN Frame of the TSEdge (point on the hull, U vector, V vector and normal)
            
A bunch of TSEdge properties: uvnFrame and index, whether TSEdge is on Border, is Manifold or not
