Class
    Foam::surfaceWriters::x3dWriter

Description
    A surfaceWriter for X3D files.

    The formatOptions for x3d:
    \table
        Property    | Description                           | Required | Default
        compression | Use file compression                  | no  | false
        range       | The min/max range for colour table    | no  | automatic
        colourMap   | The colour map for rendering          | no  | coolToWarm
    \endtable

    \heading Output file locations

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

    \subheading Geometry
    \verbatim
    rootdir
    `-- timeName
        `-- surfaceName.x3d
    \endverbatim

    \subheading Fields
    \verbatim
    rootdir
    `-- timeName
        |-- <field0>_surfaceName.x3d
        `-- <field1>_surfaceName.x3d
    \endverbatim
