New extraction functions added (that just wrap the old ones). The difference here is that the extensions can be included or ignored now. This has been added to address issue #24 where header keys can in fact include an extension prefix.

When building a document, everything that IS NOT a schema is auto-resolved in the model, this is very convenient because it creates a nice tree to explore and there is no need to perform lookups to when using `$ref` instead of inline definitions.
The issue is however being able to determine if the node was originally a reference or not, that data was lost, including the name of the reference used. This use case surfaced in issue #25, where the need to know what is and what is not referenced has different requirements for different applications.
This update now tracks that data and makes it available in `NodeReference` and `ValueReference` for every property.

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.
