OrientDB adapter

Hi, I'm developing an adapter for orientdb. Currently every test pass except for the ones related to relationships.
You can check the adapter here: https://github.com/sarhugo/jugglingdb-orientdb
My doubt is how I can modify the way that relationships are handled without having to rewrite the relation handler entirely. My desire is to implement the relationships via edges between classes or even allow to have the related records embedded into the class itself, maybe via some custom setting when defining the relationship.

I'm welcome to suggestions
Thanks

Examine the existing adapter at https://github.com/sarhugo/jugglingdb-orientdb to see which relationship tests are failing. Look at JugglingDB's relation handler source to understand the extension points. Determine how to modify relationship handling to support OrientDB edges or embedded records without a full rewrite.
