- write finiteArea meshes and fields to standard surface output
  formats (Ensight, VTK, etc).

- normally findInstance will 'bottom out' with the constant directory
  while doing its reverse time search. This mechanism however fails
  when searching for negative start values (if there are none in the
  list). Add additional logic for this so that constant will also be
  used in these situations.

Note: to have decomposePar work for all times, may need the -constant option
to trigger the proper time list.

- While a rectilinear mesh can be created with blockMesh, not every mesh
  created with blockMesh will satisfy the requirements for being a
  rectilinear mesh.

  This alternative to blockMesh uses a single block that is aligned
  with the xy-z directions and specifications of the control points,
  mesh divisions and expansion ratios. For example,

    x
    {
        points  ( -13.28 -0.10 6.0 19.19 );
        nCells  (  10  12 10 );
        ratios  ( 0.2   1  5 );
    }

    y { ... }
    z { ... }

  With only one block, the boundary patch definition is simple and the
  canonical face number is used directly. For example,

    inlet
    {
        type    patch;
        faces   ( 0 );
    }
    outlet
    {
        type    patch;
        faces   ( 1 );
    }

    sides
    {
        type    patch;
        faces   ( 2 3 );
    }

    ...

- After a mesh is defined, it is trivial to retrieve mesh-related
  information such as cell-volume, cell-centres for any i-j-k location
  without an actual polyMesh.

STYLE: remove -noFunctionObjects from blockMesh

- no time loop, so function objects cannot be triggered anyhow.

- Extended runTimePostProcessing to include access to "live"
  simulation objects such a geometry patches and sampled surfaces
  stored on the "functionObjectObjects" registry.

- Add 'live' runTimePostProcessing of cloud data.
  Extracts position and fields from the cloud via its objectRegistry writer

- For the "live" simulation objects, there are two new volume filters
  that work directly with the OpenFOAM volume fields:
      * iso-surface
      * cutting planes
  Both use the VTK algorithms directly and support multiple values.
  Eg, can make multiple iso-levels or multiple planes parallel to each
  other.

- When VTK has been compiled with MPI-support, parallel rendering will
  be used.

- Additional title text properties (shadow, italic etc)

- Simplified handling of scalar-bar and visibility switches

- Support multiple text positions. Eg, for adding watermark text.

- fits better into the general sampling framework, improves flexibilty
  and allows code reduction.

ENH: include surface fields on sampledSurfaces that support it

- currently supports pTotal, rhoU.

- implemented as lazy evaluation with an additional update() method.
  This avoids unnecessary changes until the values are actually
  required.

- apply mesh motion changes for momentum, volFieldValue,
  specieReactionRates function objects

- also removed some editing cruft from controlDict that should not
  have been there

- changed the sectorCoeffs keyword to 'point' from 'axisPt'
  for more similarity with other dictionaries.
  Continue to accept 'axisPt' for compatibility.

- make adjustment of the DebugSwitches optional.
  Enable (the old behaviour) with -debug.

- only backup/modify controlDict if it contains a DebugSwitches entry

- add -no-debug option to suppress modification entirely
