Class
    Foam::surfaceWriters::foamWriter

Description
    A surfaceWriter for OpenFOAM surfaces

    \verbatim
    formatOptions
    {
        foam
        {
            format      ascii;
            compression true;
            fieldLevel
            {
                p       1e5;    // Absolute -> gauge [Pa]
            }
            fieldScale
            {
                "p.*"   0.01;   // [Pa] -> [mbar]
            }
        }
    }
    \endverbatim

    Format options:
    \table
        Property | Description                              | Required | Default
        format   | ascii/binary                             | no  | ascii
        compression | Use file compression                  | no  | false
        scale       | Output geometry scaling               | no  | 1
        transform   | Output coordinate transform           | no  |
        fieldLevel  | Subtract field level before scaling   | no  | empty dict
        fieldScale  | Output field scaling                  | no  | empty dict
    \endtable

    \section Output file locations

    The \c rootdir normally corresponds to something like
    \c postProcessing/<name>

    \subsection Geometry
    \verbatim
    rootdir
    `-- timeName
        `-- surfaceName
            |-- "points"
            |-- "faceCentres"
            `-- "faces"
    \endverbatim

    \subsection Fields
    \verbatim
    rootdir
    `-- timeName
        `-- surfaceName
            |-- scalarField
            |   |-- field
