By default, clicking the center button will behave differently, depending on the UltraRadialMenu.CenterTool. If the center tool has no parent tool, then the expanded state of the menu will be toggled. If the center tool has a parent tool, then the center button will act as a 'back' button, navigating up the tool tree one level.
