Django Lazy ModelChoiceField

	"""
	In practice with four subclasses of LazyModelChoiceField
	across a large project, we found existing __deepcopy__ based
	alternatives such as
	https://djangosnippets.org/snippets/2973/
	simply didn't work in all the circumstances we needed them to.

	Tested against Python 2.7 and Python 3.4 with Django 1.6.8

	Hopefully this works for you too :)
