Detailed Description

Performs an edge swap, implemented as a combination of swap and collapse.

There are no explicit checks for valence. However, the collapse checks implicitly for validity of the swap. The swap will be not performed if the collapse does not fulfill the link condition.

The edge swap cannot be performed on boundary edges.
