      ENH: region-wise decomposition specification for decomposeParDict · 0f3932b3
      Mark OLESEN authored 
        Within decomposeParDict, it is now possible to specify a different
  decomposition method, methods coefficients or number of subdomains
  for each region individually.

  The top-level numberOfSubdomains remains mandatory, since this
  specifies the number of domains for the entire simulation.
  The individual regions may use the same number or fewer domains.

  Any optional method coefficients can be specified in a general
  "coeffs" entry or a method-specific one, eg "metisCoeffs".

  For multiLevel, only the method-specific "multiLevelCoeffs" dictionary
  is used, and is also mandatory.

----

ENH: shortcut specification for multiLevel.

  In addition to the longer dictionary form, it is also possible to
  use a shorter notation for multiLevel decomposition when the same
  decomposition method applies to each level.

      ENH: reduced verbosity when decomposing/reconstructing empty meshes · 241b44ea
      Mark OLESEN authored 
      - only warn about missing cells/points if the mesh is also missing
  boundary patches.
- reduce verbosity when decomposing to an empty mesh
- skip face matching when either mesh has no faces
