* A TitledPane is a panel with a title that can be opened and closed.
*
* The panel in a TitledPane can be any {@link Node} such as UI controls or groups
* of nodes added to a layout container.
*
* It is not recommended to set the MinHeight, PrefHeight, or MaxHeight
* for this control. Unexpected behavior will occur because the
* TitledPane's height changes when it is opened or closed.
*
* Example:
*
* TitledPane t1 = new TitledPane("T1", new Button("B1"));
* t1.setMode(TitledPaneMode.FADE);
