Integration of VOF MULES new interfaces. Update of VOF solvers and all instances
of MULES in the code.
Integration of reactingTwoPhaseEuler and reactingMultiphaseEuler solvers and sub-models
Updating reactingEuler tutorials accordingly (most of them tested)

New eRefConst thermo used in tutorials. Some modifications at thermo specie level
affecting mostly eThermo. hThermo mostly unaffected

New chtMultiRegionTwoPhaseEulerFoam solver for quenching and tutorial.

Phases sub-models for reactingTwoPhaseEuler and reactingMultiphaseEuler were moved
to src/phaseSystemModels/reactingEulerFoam in order to be used by BC for
chtMultiRegionTwoPhaseEulerFoam.

Update of interCondensatingEvaporatingFoam solver.

- generalize some of the library extensions (.so vs .dylib).
  Provide as wmake 'sysFunctions'

- added note about unsupported/incomplete system support

- centralize detection of ThirdParty packages into wmake/ subdirectory
  by providing a series of scripts in the spirit of GNU autoconfig.
  For example,

      have_boost, have_readline, have_scotch, ...

  Each of the `have_<package>` scripts will generally provide the
  following type of functions:

      have_<package>          # detection
      no_<package>            # reset
      echo_<package>          # echoing

  and the following type of variables:

      HAVE_<package>          # unset or 'true'
      <package>_ARCH_PATH     # root for <package>
      <package>_INC_DIR       # include directory for <package>
      <package>_LIB_DIR       # library directory for <package>

  This simplifies the calling scripts:

      if have_metis
      then
          wmake metisDecomp
      fi

  As well as reducing clutter in the corresponding Make/options:

      EXE_INC = \
          -I$(METIS_INC_DIR) \
          -I../decompositionMethods/lnInclude

      LIB_LIBS = \
          -L$(METIS_LIB_DIR) -lmetis

  Any additional modifications (platform-specific or for an external build
  system) can now be made centrally.

'set -x' should be used for debugging.

Added command printing into wmake and Allwmake as a replacement for
'set -x' to log current target.

Resolved bug-report http://www.openfoam.org/mantisbt/view.php?id=2042

and two-phase functionality separated from multiphase functionality

Needs to be consolidated with multiphaseInterFoam with thermal and
compressibility effects made run-time selectable

- Added conformationSurface and searchableSurface classes in place
  of querySurface.
- Added cellSizeControl class.
- Change cvMesh argument of relaxation model constructor to Time.
- Add writePrecision option to surfaceConvert.
- Add onLine function to surfaceFeatureExtract.
- Remove querySurface.
- Move createShellMesh and extrude2DMesh to their own libraries.
- Replace controls and tolerances with a cv2DControls object.
- Add patchToPoly2DMesh class to extrude2DMesh.

Relaxation and solution parameters for the final iteration in PIMPLE loops are
now selected according to the value of the "finalIteration" entry in the
mesh::data dictionary.

rhoPimpleFoam significantly updates and now replaces rhoPisoFoam.
