* A ToolBar is a control which displays items horizontally
* or vertically. The most common items to place within a {@code ToolBar}
* are {@link Button Buttons}, {@link ToggleButton ToggleButtons} and
* {@link Separator Separators}, but you are not restricted to just these, and
* can insert any {@link Node} into them.
*
*
* If there are too many items to fit in the ToolBar an overflow button will appear.
* The overflow button allows you to select items that are not currently visible in the toolbar.
*
*
* ToolBar sets focusTraversable to false.
*
*
*
* Example of a horizontal ToolBar with eight buttons separated with two vertical separators.
*
* ToolBar toolBar = new ToolBar(
* new Button("New"),
* new Button("Open"),
* new Button("Save"),
* new Separator(),
