Detailed Description

Description of cuts across cells.

Description of cut is given as list of vertices and list of edges to be cut (and position on edge).

Does some checking of correctness/non-overlapping of cuts. 2x2x2 refinement has to be done in three passes since cuts can not overlap (would make addressing too complicated)

Introduces concept of 'cut' which is either an existing vertex or a edge.

Input can either be

  1. list of cut vertices and list of cut edges. Constructs cell circumference walks ('cellLoops').
  2. list of cell circumference walks. Will filter them so they don't overlap.
  3. cellWalker and list of cells to refine (refineCell). Constructs cellLoops and does B. cellWalker is class which can cut a single cell using a plane through the cell centre and in a certain normal direction

CellCuts constructed from cellLoops (B, C) can have multiple cut-edges and/or cut-point as long as there is per face only one (or none) cut across a face, i.e. a face can only be split into two faces.

The information available after construction:

AnchorPoints: connected loops have to be oriented in the same way to be able to grow new internal faces out of the same bottom faces. (limitation of the mapping procedure). The loop is cellLoop is oriented such that the normal of it points towards the anchorPoints. This is the only routine which uses geometric information.
