Class
    Foam::fileFormats::STLsurfaceFormat

Description
    Provide a means of reading/writing STL files (ASCII and BINARY).

    Output stream options: ASCII/BINARY, compression for ASCII only

    Output dictionary options: ignored

Note
    For efficiency, the zones are sorted before creating the faces.
    The class is thus derived from MeshedSurface.
