Class
    Foam::coordSetWriters::gnuplotWriter

Description
    A coordSet(s) writer in gnuplot format.

    The formatOptions for gnuplot:
    \table
        Property    | Description                       | Required | Default
        buffer      | Use buffered output               | no  | true
        compression | Use file compression              | no  | false
        precision   | Write precision in ascii          | no  | same as IOstream
    \endtable

    When called with a single coordSet, will buffer the output of
    all fields and output together in the order of label/scalar/vector/...
    each of which is sorted alphabetically according to the field name.

    When called as a track writer (eg, with multiple coordSets),
    will emit one file per field.
