Note that now mirrorMesh does not delete empty patches anymore.

Feature paraview clouds

See merge request !145

- Can occur if the selected geometry does not actually exist.
  A non-critical bug since paraview catches this anyhow and
  just emits a warning message.

- previous only checked for clouds at the last instance and only
  detected lagrangian fields from the first cloud.

  Now check for clouds at all instances and detect all of their fields
  as well.

Feature surface field value operations

See merge request !141

Feature surface scaling

See merge request !139

- affects surfaceFieldValue, volFieldValue.

  Use 'none' (if desired) to explicitly suppress the weightField, but
  generally better to use a different operation.

- relocate as Test-surfaceMeshConvert.

Resolves feature request https://bugs.openfoam.org/view.php?id=2656

ENH: Adding required interpolation for alpha.water in fvSchemes for overInterDyMFoam floatingBody tutorial

ENH: Adds basic information for faceZone and cellZones during checkMesh (fixes #560)

See merge request !142

BugFix: corrected keyword for flowRateInletVelocity BC fixes #577

Closes #577

See merge request !143

There are a few issues:
- error would only throw exceptions if not parallel
- if we change this we also need to make sure the functionObjectList
  construction is synchronised
- bounding box overlap was not returning the correct status so the code
  to avoid the issue of 'badly formed bounding box' was not triggered.

     fixes #560

Now we directly releate the intersected face triangle to the tet of the
cell the point is on/in. We hope that the tracking handles this ok. Fixes #549.
