> Introduce a new `selected` variable in `FolderNode` and `GraphNode`. Whenever the currently viewed graphs change, the function `changed(InputGraphProvider lastProvider)` in `OutlineTopComponent` is called. Here we set the `FolderNode` and `GraphNode` to be (un)selected. This fires a `fireDisplayNameChange` and a `fireIconChange` which updates the text/icons.
