UoW code spike

	# NOTE: this is a code spike, and the following code will probably
	# not make it into dm-core in it's current form. I wanted to see if it
	# were possible to use a topographical sort to ensure parents were
	# saved before children, before/after filters were fired in the correct
	# order, and foreign keys set before children are saved, but after parents
	# are saved.

	# The hooks should fire in the following order:
