FOAM_INST_DIR is the location of the OpenFOAM installation which defaults to
the directory containing the etc/bashrc,cshrc file.  If this default is
not appropriate FOAM_INST_DIR can be set explicitly.

Description
    Implementation of the k-omega-SST-DES turbulence model for
    incompressible and compressible flows.

    DES model described in:
    \verbatim
        Menter, F. R., Kuntz, M., and Langtry, R. (2003).
        Ten Years of Industrial Experience with the SST Turbulence Model.
        Turbulence, Heat and Mass Transfer 4, ed: K. Hanjalic, Y. Nagano,
        & M. Tummers, Begell House, Inc., 625 - 632.
    \endverbatim

    Optional support for zonal filtering based on F1 or F2 is provided as
    described in the paper.

    For further details of the implementation of the base k-omega-SST model
    see Foam::kOmegaSST.

    The DES coefficient 'CDES' defaults to 0.61 but may be changed as
    necessary.

    The zonal filter filter defaults to '2' which uses "(1 - F2)" as
    suggested in the paper but '0' (no filtering) and '1' which uses
    "(1 - F1)" are also supported.

Replaces the dictionary access functionality of foamInfoExec and
provides additional options to edit individual entries.

for consistency with the 'Log' macro.

includeFuncEntry: Added support for function arguments compatible with the '-func' post-processing option

e.g.

functions
{
    #includeFunc mag(U)
}

executes 'mag' on the field 'U' writing the field 'mag(U)'.

The equivalent post-processing command is

postProcess -func 'mag(U)'

tutorials/electromagnetics/mhdFoam/hartmann: Added functionObject

Replaced separate 'postProcess' step with a functionObject executed at
run-time.
