Bulk update with .push()

	/**
	* Send a bulk update to Firebase from an array or an object literal.
	*
	* When .push() is called on a Firebase reference without a parameter passed no
	* trip to the server is made.
	*
	* ex:
	* var childRef = ref.push();
	*
	* A reference is returned which has a push-id that can be returned by calling .name().
