27 Description
28  Set of directions for each cell in the mesh. Either uniform and size=1
29  or one set of directions per cell.
30 
31  Used in splitting cells.
32  Either all cells have similar refinement direction ('global') or
33  direction is dependent on local cell geometry, or loads selected fields
34  by name ('fieldBased'). Controlled by dictionary.
