Class
    Foam::Function1s::Table

Description
    Templated interpolated tabulated data Function1.

    Items are stored in a list of Tuple2's. First column is always stored as
    scalar entries. Data is read in Tuple2 form:

Usage
    \verbatim
        <name>   table
        (
            (0.0 (1 2 3))
            (1.0 (4 5 6))
        );
    \endverbatim

    or in dictionary form which supports the setting of options, e.g.
    \verbatim
        <name>   table;

        values
        (
            (0.0 (1 2 3))
            (1.0 (4 5 6))
        );

        outOfBounds         clamp;     // optional out-of-bounds handling
        interpolationScheme linear;    // optional interpolation method
    \endverbatim

    or in sub-dictionary form which avoids clashes between table entries and
    other entries in the dictionary:

    \verbatim
        <name>
        {
            type    table;

            values
            (
                (0.0 (1 2 3))
                (1.0 (4 5 6))
            );

            outOfBounds         clamp;     // optional out-of-bounds handling
            interpolationScheme linear;    // optional interpolation method
        }
    \endverbatim

    The data may be read from a separate file in either native or CSV format:

    \verbatim
        <name>
        {
            type                table;
            file                "<file path>"; // Name/path of thedata file
            format              foam;      // data format (optional)
            outOfBounds         clamp;     // optional out-of-bounds handling
            interpolationScheme linear;    // optional interpolation method
        }
    \endverbatim
