Changed all console.error() calls to throws
Callbacks now return useful information about how many records were created
BUGFIX: Scenario now checks that a model is available before blindly trying to examine it
BUGFIX: An item with multiple linkages would be partially resolved and shoved back into the defer queue - causing the already resolved keys to be resolved again
BUGFIX: Finalize/Success/Fail now only fire when the queue appears to be empty - still not perfect but will have to do for now
Updated TODO list
