[Rdfapi-php-interest] patches and graph visualization

Hi,
the patches for the N3- parser submitted by Hannes Gassert and a graph 
visualization extension for drawing visualizations of models in several 
file formats like png, svg or jpeg submitted by Anton Köstlbacher were 
added to the CVS. To test the graph visualization functions you also 
need to install the open source software Graphviz available at 
http://www.graphviz.org. Thanks to Hannes Gassert for his patches and 
Anton Köstlbacher for his great extension.

Regards,
Tobias Gauss
