// This propagation pattern will created a new Construction Edge. It is passed
// in the Edge Name, the Source Vertex (from), the Destination Vertex (to), 
// and the Offset. The propagation pattern stores the Edge Name, and makes the
// connection from the Source Vertex to the Destination Vertex in the class 
// dictionary. Also, it stores the Label Box Coordinates (Offset).
