Working example for 1/2 template substitution
* Detection of "sandwiched" volumes (that share only a edge with the plane)
* Related: Traversal takes into account problematic 1/2 templates faces
* Repair impossible markings (wip)
* 3 templates outside of iteration plane are not refined
* Issue: I think 3 templates should be allowed outside of the plane, since we check for 3 templates validity only inside the plane
* Solution: Either a propagation issue ( keep older 1/2 templates propageable )  or else its a non issue and properly detect the 3 templates outside the plane.
* WIP Expansion of initial identified set, for additional level of refinement
* WIP Creation of new iteration plane for the next level.
=> Uses Union_find, to create connected components, for the algorithm to avoid iterating outside of the current level context
