Detailed Description

'Cuts' a mesh with a surface.

Divides cells into three types

cut, i.e. any of the edges of the cell is split or any edge of the surface pierces any of the faces of the cell.
outside: cell can be reached by Meshwave from any of the supplied outside points (without crossing any cut cell)
inside: all other.

Used in various meshing programs.

Has various utility functions to deal with 'features' on this level where the mesh still has all inside and outside cells.

Concepts

point classification:
- point used by meshType cells only
- point used by non-meshType cells only
- point used by both types ('mixed')
hanging cells: meshType cells using mixed points only. These cells would have all their vertices on the surface when extracting the meshType cells.
regionEdges: edges where the cells using it are of mixed type. Or more precise when walking around the edge and looking at the different types of the cells there are more than two regions with same type.

Seen from above:

Ok:
     A | A
       |
     --+---
       |
     B | B

Not ok:
     A | B
       |
    ---+---
       |
     B | A

because this latter situation would cause the surface after subsetting type A or B to be multiply connected across this edge. And also when snapping the edge end points to the surface it might cause some twisted faces if the surface is normal to the edge (and smoothing the surface would not help since the points on the edge would be 'pulled' from two different sides)

regionPoints: like regionEdges but now for points. Points where subsetting the mesh would cause a multiply connected outside surface (connected across point, not edge)
