Automated export of an RDF graph (describing the RDFS vocabulary). This uses many parts that were programmed by me over the last year:
  * RDF graph to generic Graph Interchange Format.
  * Writing a GraphViz graph based on a generic graph representation (GIF).
  * Convert using GraphViz and open a PDF using an external process.
  * Choose what gets included in the visualization using a cloned graph.
  * Export of RDF terms, with various options.
  * Cowspeak notifying of a loaded graph.

* [COWSPEAK,FIX] Removed nondeterminism in cow and message writing (DCGs).
* [DB_EXT,FIX] db_replace[_novel]/1 would remove too many facts. Now a pattern of parameters that have to be replaced/retained has to be given.
* [DCG_WRAP,FOX] White characters would be placed at the start of a line if the previous word would tightly fit the previous line.
* [GRAPH_EXPORT,RDF_EXPORT,FIX] Colorschemes must be part of each vertex and of each edge description, apparently! GraphViz.
* [RDF_EXPORT,NEW] Added export_rdf_graph/3 wrapper.
* [RDFS_VOC,NEW] Ability to export the RDFS vocabulary to a PDF file. Based on an RDF file from the W3C, visualization is fully automated.
