Class
    Foam::setWriter

Description
    Base class for graphics format writing. Entry points are
    - write(..). \n
      Write to an Ostream a table of points with corresponding values.
    - write(scalar/vector/sphericalTensor/symmTensor/tensor). \n
      Write single scalar/vector/sphericalTensor/symmTensor/tensor.
      Default is to write space separated components.

    Example:
    \verbatim
        // Construct setWriter of xmgr type
        autoPtr<setWriter<scalar>> scalarFormatter =
            setWriter<scalar>::New("xmgr");

        // Output list of points and corresponding values
        scalarFormatter().write
        (
            coordSet(...)
            "U.component(0)",   // name of values
            vals                // values
        );
    \endverbatim
