  52  * The ChoiceBox is used for presenting the user with a relatively small set of
  53  * predefined choices from which they may choose. The ChoiceBox, when "showing",
  54  * will display to the user these choices and allow them to pick exactly one
  55  * choice. When not showing, the current choice is displayed.
  56  * <p>
  57  * By default, the ChoiceBox has no item selected unless otherwise specified. 
  58  * Although the ChoiceBox will only allow a user to select from the predefined
  59  * list, it is possible for the developer to specify the selected item to be
  60  * something other than what is available in the predefined list. This is
  61  * required for several important use cases.
  62  * <p>
  63  * It means configuration of the ChoiceBox is order independent. You
  64  * may either specify the items and then the selected item, or you may
  65  * specify the selected item and then the items. Either way will function
  66  * correctly.
