Previous behavior which may be useful for moving-mesh cases can be
selected using the optional entry:
    writeVolume  yes;

The initial volume is written in the log and data file header e.g.:

 #   Source : all
 #   Cells  : 3829
 #   Volume : 9.943164e-01

Also added
    sumMag        | sum of component magnitudes

Previous behavior which may be useful for moving-mesh cases can be
selected using the optional entry:
    writeTotalArea  yes;

The initial total area is written in the log and data file header e.g.:

 #   Source : faceZone f0
 #   Faces  : 8
 #   Area   : 1.063860e-02

Description
    Specify an etc file to include when reading dictionaries, expects a
    single string to follow.

    Searches for files from user/group/shipped directories.
    The search scheme allows for version-specific and
    version-independent files using the following hierarchy:
    - \b user settings:
      - ~/.OpenFOAM/\<VERSION\>
      - ~/.OpenFOAM/
    - \b group (site) settings (when $WM_PROJECT_SITE is set):
      - $WM_PROJECT_SITE/\<VERSION\>
      - $WM_PROJECT_SITE
    - \b group (site) settings (when $WM_PROJECT_SITE is not set):
      - $WM_PROJECT_INST_DIR/site/\<VERSION\>
      - $WM_PROJECT_INST_DIR/site/
    - \b other (shipped) settings:
      - $WM_PROJECT_DIR/etc/

    An example of the \c \#includeEtc directive:
    \verbatim
        #includeEtc "etcFile"
    \endverbatim

    The usual expansion of environment variables and other constructs is
    retained.

Use the new -withFunctionObjects command-line option to execute functionObjects

Pe: Create and write volScalarField in addition to the surfaceScalarField for ease of post-processing
Update handling of turbulence models

This allows checkMesh and other mesh manipulation utilities to operate
on the mesh without any time directories being present.

To include 0 use the -zeroTime option

For multi-region cases the default location of blockMeshDict is now system/<region name>

If the blockMeshDict is not found in system then the constant directory
is also checked providing backward-compatibility

Note that currently when transportProperties is changed sigma is re-read
from this dictionary but cAlpha is read from fvSolution but cAlpha is
not re-read when fvSolution is changed but transportProperties is not
touched.  To avoid this problem cAlpha would need to be moved to the
transportProperties dictionary which is not ideal or moved out of the
interfaceProperties class back to the top-level solver.

Updated tutorials to converge pressure during PIMPLE loop to avoid
phase-fraction unboundedness which limits thermodynamics convergence.
