This is a bit complicated. When allocating cells to zones
(meshRefinementBaffles::zonify) in finishes with findCellTopo which
tried to fix the odd cell which wasn't put into the correct region. This
was actually modifying whole regions to be a certain cellZone so if
there was some 'bleeding' it would re-assign a whole region to be e.g.
background and get deleted. Instead it now will only reassign single
cells if these are
- unassigned
- inbetween multiple, differing cellZones

Fixes the simpleFoam/rotorDisk meshing (gitlab #141)

Feature mppic inter foam

New MPPICInterFoam solver. Add MPPIC cloud to a VOF approach. Particles volume are considered into transport Eq fluxes.
    Solves for 2 incompressible, isothermal immiscible fluids using a VOF
    (volume of fluid) phase-fraction based interface capturing approach.
    The momentum and other fluid properties are of the "mixture" and a single
    momentum equation is solved.

Solver:

Tutorial:

Feature boundary radiation properties

Change of the frame work for the specification of radiation properties

See merge request !42

- most notably the '%' which is used as a separator in places
  caused problems.

EHN: only use valid ensight file/variable names for writers

- fixed:   foamToEnsightParts, ensightSurfaceWriter
- pending: foamToEnsight

BUG: no geometry written for foamToEnsightParts with moving mesh (fixes #142)

- an incorrect path was causing the issue

- increases flexibility and adds consistency with the word class.

reactionSensitivityAnalysis FO

 This function object creates four data files named:

    "consumption"    :   consumption rate
    "production"     :   destruction rate
    "productionInt"  :   integral between dumps of the production rate
    "consumptionInt" :   integral between dumps of the consumption rate

    The function object indicates reaction rates of creation or destruction of species in each reaction.

code:
        src/postProcessing/functionObjects/utilities/reactionSensitivityAnalysis/
tutorial:
         /tutorials/combustion/chemFoam/gri

The output format file is (consumption.dat):

time :        1e-2
dellat T:   1e-5
Reaction         specie1  specie2 ....
1                          RR11       RR12
2                          RR21       RR22

Feature lagrangian

Minor adjustments to static information attached to lagrangian parcels/particles.
Fixes #108 (duplicate of http://www.openfoam.org/mantisbt/view.php?id=1990), #109, #110, #111.

Future reworking would require a better mechanism to also deal with dynamic information such as particle collisions etc.

Partly solves #65. Ensight writer is fixed but all the other ones probably
need doing as well.

ENH: Changing boundaryRadiationProperties to read an scalar when a lookup mode is used for boudanry radiation properties.
Tutorials updated accordingly

instead of removing them. Now done similar to 23x:
- in 'removing unreachable parts of mesh' keep regions unset (so they get removed)
- in final zoning set to background region

See Gitlab #66.

Feature iotweaks

Enhancements for #114 and #115. Tagged as WIP, since there may be some need for discussion/rework prior to merging.

See merge request !35

Merge foundation

Integrating latest code from the OF Foundation - main changes:

Lots of renaming/refactoring:
- to retrieve reference from tmp, now need to use tmp.ref() as opposed to tmp()
- fvc::flux function to replace fvc::interpolate(<field>) & mesh.Sf()
- integration of new c++ features: no more spaces between closing template braces, e.g. class1<class2<Type> > becomes class1<class2<Type>>
- DataEntry renamed to Function1

New functionality:
- Updated 6DoF
- fvOptions support in turbulence models
