Represents the underlying linework for edges in a topology graph, and carries the topology information derived from the two parent geometries. The edge may be the result of the merging of two or more edges which have the same underlying linework (although possibly different orientations). In this case the topology information is derived from the merging of the information in the source edges. Merged edges can occur in the following situations
The source edges may have the same parent geometry, or different ones, or a mix of the two.

Merges an edge into this edge, updating the topology info accordingly.
Marks this as a shell edge if any contributing edge is a shell. Update hole status first, since it depends on edge dim

Compares two coincident edges to determine whether they have the same or opposite direction.
