Class
    Foam::fileFormats::STLsurfaceFormat

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

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

SourceFiles
    STLsurfaceFormat.C
    STLsurfaceFormatASCII.L
