gfLib - Cleaning house in CVS

In the continuing effort to keep GF lean and mean, a bunch of files have been removed from GF's CVS.

The gfXML project and files have been removed from CVS. All new applications should now be using the gfXMLIO project instead.

The data files for the example projects have been removed from CVS and are now packaged separately. See the File Release section for the latest data files.
