Detailed Description

A FaceSwap (or a Swap 2-3) performs a swap a face sharing by two tets to an edge split the volume of the two tets into three new tets.

This is the reverse operation of a EdgeSwap 3-2.

FaceSwap executes two splits then two collapses.

FaceSwap cannot be performed on boundary faces.
