Creates an item in the tree and adds it as a child of [param parent], which can be either a valid [TreeItem] or [code]null[/code].
If [param parent] is [code]null[/code], the root item will be the parent, or the new item will be the root itself if the tree is empty.
The new item will be the [param idx]th child of parent, or it will be the last child if there are not enough siblings.
The new item will be the [param index]-th child of parent, or it will be the last child if there are not enough siblings.
