\& \- Added methods to bridge classes for creating statements and blank nodes.
\& \- Added as_string method to bridge classes for getting string versions of nodes.
\& \- Broke out triple fixup code into fixup_triple_bridge_variables().
\& \- Updated FILTER test to use new Geo::Distance API.
\&
\& Revision 1.3  2005/04/26 02:54:40  greg
\& \- added core support for custom function constraints support
\& \- added initial SPARQL support for custom function constraints
\& \- SPARQL variables may now begin with the \*(Aq$\*(Aq sigil
\& \- broke out URL fixups into its own method
\& \- added direction support for ORDER BY (ascending/descending)
\& \- added \*(Aqnext\*(Aq, \*(Aqcurrent\*(Aq, and \*(Aqend\*(Aq to Stream API
\&
\& Revision 1.2  2005/04/25 00:59:29  greg
\& \- streams are now objects usinig the Redland QueryResult API
\& \- RDF namespace is now always available in queries
\& \- row() now uses a stream when calling execute()
\& \- check_constraints() now copies args for recursive calls (instead of pass\-by\-ref)
\& \- added ORDER BY support to RDQL parser
\& \- SPARQL constraints now properly use the \*(AqFILTER\*(Aq keyword
\& \- SPARQL constraints can now use \*(Aq&&\*(Aq as an operator
\& \- SPARQL namespace declaration is now optional
\&
\& Revision 1.1  2005/04/21 02:21:44  greg
\& \- major changes (resurecting the project)
\& \- broke out the query parser into it\*(Aqs own RDQL class
\& \- added initial support for a SPARQL parser
\&   \- added support for blank nodes
\&   \- added lots of syntactic sugar (with blank nodes, multiple predicates and objects)
\& \- moved model\-specific code into RDF::Query::Model::*
\& \- cleaned up the model\-bridge code
\& \- moving over to redland\*(Aqs query API (pass in the model when query is executed)
