Replaces ActiveModel::Serializers with ActiveModel::Serializer

	module JsonSerializationUnifier
	# ActiveModel::Serializer only works in the controller's render method
	# This modue replaces ActiveModel::Serializers with ActiveModel::Serializer
	# yup, a little confusing. Include in in your model classes so to_json and
	# as_json work as expected in the console and elsewhere.

	extend ActiveSupport::Concern

	def as_json(value=nil, use_options = true)
	return active_model_serializer.as_json if active_model_serializer
