/** Test to create a writer document and insert an OLE Chart.

    Be careful!  This does not really work.  The Writer currently has no
    interface for dealing with OLE objects.  You can add an OLE shape to the
    Writer's drawing layer, but it is not treated correctly as OLE object.
    Thus, you can not activate the chart by double-clicking.  The office may
    also crash when the document is closed!
