Class
    Foam::uniformInterpolationTable
 
Description
    Table with uniform interval in independant variable, with linear
    interpolation
 
    Example usage (scalar): values specified within a dictionary:
 
    \verbatim
    {
        x0          0;          // lower limit
        dx          0.2;        // fixed interval
        log10       true;       // take log(10) when interpolating?
        data                    // list of dependent data values
        (
            7870                // value at x0
            7870                // value at x0 + dx
            ...
            7870                // value at x0 + n*dx
        );
    }
    \endverbatim
