Several significant changes

* More automation; reduces the amount of work to define a Domain Model class
* Removed ORM abstraction layer; edr is now dedicated specifically to AR
* Minor refactorings

More API changes and refactorings to come.

I'm uncertain whether this deviates enough from the original version to warrant a full blown fork/separate gem.  I'd say it depends upon how far it deviates from your goals for the gem.
