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.
Schemas are now rendered on demand. There is no reasonable way to navigate the mayhem that is circular dependencies through multiple inheritance and polymorphism. So now using a msuch simpler design (and MUCH faster), there is a `SchemaProxy` for every schema reference. This holds a reference to the low model and index, that renders the schema on demand. Once rendered, it's done. Any children can also be rendered on demand, and so down the rabbit hole you do (if you want).
All circular dependencies are know by the index, so you can decide when you want to stop, or just keep going for ever, however it's now a choice, not something decided for you.

Using some designs unearthed from building the higher level model, I have brough that design down to the lower level to speed things up. It only took 8 years, but finally, I think I have mastered mult-threading. No more deadlocks, and no more need for waitgroups for everything.
I think it should be pretty much bullet proof at the moment (until the next failure). Also added external index lookups from main index for external docs. found this bug after refining lookups in schemas.
now things are robust, we can move things around a little to prepare for the next set of incoming models. The extraction and builder functions have all been moved to the low packakge, and out of the v3 package.
