locating nodes was looking through two levels to locate something. This is not the correct behavior, after making the change - lots of tests needed to be updated to be correct in what they put into as a the root node.
Model for v2 and v3 has been validated, now to build out a simple high level creation API, as well as port in 3.1 models (I think there are two). and this is ready for heavier testing.
Same functions will power every other model. Found some opprotunities to add control over circular references, when and how to fire errors and what not. All in all, some robust code additions will improve the library significantly.
