Extracts files embedded in EMF and offers a
very rough capability to extract text if there
is text stored in the EMF.
<p/>
To improve text extraction, we'd have to implement
quite a bit more at the POI level.  We'd want to track changes
in font and use that information for identifying character sets,
inserting spaces and new lines.
