      ENH: geometric decomposition constraint using topoSetFaceSource (issue #921) · 5377f371
      Mark OLESEN authored 
      - replaced use of searchableSurface with a more general and
  more efficient topoSetFaceSource instead.
  Since searchableSurface is also available as a topoSetFaceSource,
  there is no loss in functionality, but using topoSetFaceSource allow
  directly looping over the faces without creating of an additional
  List of volumeTypes.

      ENH: add geometric decomposition constraint (issue #921) · d6bb7ac8
      Mark OLESEN authored 
      - geometric decomposition constraints may be used to prevent the
  decomposition of regions of the mesh.

  The geometric constraint is applied according to the face centres,
  which define the connectivity between cells.

ENH: add 'grow' option for geometric decomposition constraint (issue #921)

- the 'grow' option includes an additional check to include cell faces
  for any cell that already has two or more of its faces "unblocked".
  This could indicate a connection over a corner, but does not distinguish
  between connectivity introduced by the constraint and the connectivity
  defined by other constraints.
