 		[b]Note:[/b] The node doesn't need to own itself.
 		[b]Example of saving a node with different owners:[/b] The following example creates 3 objects: [code]Node2D[/code] ([code]node[/code]), [code]RigidBody2D[/code] ([code]rigid[/code]) and [code]CollisionObject2D[/code] ([code]collision[/code]). [code]collision[/code] is a child of [code]rigid[/code] which is a child of [code]node[/code]. Only [code]rigid[/code] is owned by [code]node[/code] and [code]pack[/code] will therefore only save those two nodes, but not [code]collision[/code].
