Support new GEOFF syntax

Also, the GEOFF extension: https://github.com/neo4j/neo4j-geoff

Consider deprecating or removing the client-side GEOFF implementation.

Damn, beat me to it... was going to raise this as an issue! :-P

Yeah, I knew it was going to have to happen. What I'll probably end up doing is checking to see if the extension is available and forwarding to that if it is, otherwise parse it on the client side. I may have to change the API around a bit, but I don't think many people are using it in Neo4jPHP, so it hopefully won't affect too many users.

That's basically what I do in py2neo:

    def load(self, file, **params):
        if self.graph_db._geoff_uri is None:
            batch = self.compile(file, **params)
            results = batch.submit()
            return neo4j.Node(results[batch.first_node_id]['location'])
        else:
            response = graph_db._post(
                graph_db._geoff_uri,
                {'rules': file.read(), 'params': dict(params)}
            )
            return response['params']

On construction of a GraphDatabaseService instance, I query the extensions and store recognisable URIs. In this case the Geoff plugin URI is stored in graph_db._geoff_uri so it's a simple case of checking whether or not that has a value.

Feel free to rip off my code as much as you like :-)

I plan to :-)
