Class
    Foam::setWriter
 
Description
    Base class for writing coordinate sets with data
 
    Example:
    \verbatim
        setWriter::New("vtk")->write
        (
            "myDirectory",
            "mySet",
            coordSet(true, "position", points),
            "p", p,
            "U", U
        );
    \endverbatim
