dijkstra algorithm support

[flipside]

I'm looking into using neo4j's built in dijkstra algorithm, it looked like there's already some support in node-neo4j for shortest path but dijkstra support would be great.

Sorry for the delay @flipside, but great request! We support passing 'dijkstra' as an optional algorithm parameter to the Node::path() method:

https://github.com/thingdom/node-neo4j/blob/0.2.13/lib/Node._coffee#L202

But I didn't realize that full Dijkstra support requires passing an additional cost_property parameter.

I think the signature of the path() method should probably be changed to accept an options hash now instead of a bunch of parameters.

Thanks again — and pull request welcome!

realized i don't actually need this yet but if i do, will take a crack at it.

Sorry for the delay @Karthic-Hackintosh.

Good news: it's now possible to achieve this in node-neo4j v2, even though it's not implemented directly, because you can now make arbitrary & custom HTTP / REST API calls (issue #100).

So I'm going to go ahead mark this issue as fixed in v2. Let me know if you have any q's!
