Replaces this node by the given [param node]. All children of this node are moved to [param node].
Replaces this node by the given [param node]. If [param keep_children] is [code]true[/code] all children of this node are moved to [param node].
If [param keep_groups] is [code]true[/code], the [param node] is added to the same groups that the replaced node is in (see [method add_to_group]).
[b]Warning:[/b] The replaced node is removed from the tree, but it is [b]not[/b] deleted. To prevent memory leaks, store a reference to the node in a variable, or use [method Object.free].
