Class
    Foam::TableReaders::Foam
 
Description
    Reads an interpolation table from a file in OpenFOAM-format. This is a list
    of Tuples in which complex types are delimited by parentheses. By default,
    a Tuple2 is assumed in which the first column is the (scalar) x-axis and
    the second column is the y-axis. But finer control over a n-component Tuple
    can be achieved by specifying the column indices.
 
Usage
    A file containing the following will be read with the first element in each
    tuple as the x-coordinate and the second as the y-values:
    \verbatim
        (
            (0.0 (1 2 3))
            (1.0 (4 5 6))
        )
    \endverbatim
 
    A more complex table file might look as follows:
    \verbatim
        (
            (0 (1 2 3) 4 (5 6 7 8 9 10))
            (1 (2 3 4) 5 (6 7 8 9 10 11))
            (2 (3 4 5) 6 (7 8 9 10 11 12))
        )
    \endverbatim
 
    In this case, the columns to be used can be specified using the \c columns
    entry. In this example, the second scalar column is taken as the x-axis,
    and the six-component symmTensor-s are used as the values:
    \verbatim
        columns     (2 3);
    \endverbatim
