Class
    Foam::Function2s::Radial

Description
    Function2 which returns a Function1 of the magnitude of the two-dimensional
    vector with components equal to the input arguments.

    Example
    \verbatim
        <name>
        {
            type    radial;
            value   table
            (
                (0.00 (0 0 0))
                (0.35 (0 0 1))
                (0.71 (0 0 0))
            );
        }
