'Cuts' a mesh with a surface.
Divides cells into three types
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.
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)
