/**
 *  The IFocusManagerGroup interface defines the interface that

 *  For example, a RadioButton implements IFocusManagerGroup
 *  because a set of RadioButtons in the same group 
 *  can only have one RadioButton selected at any one time,
 *  and the FocusManager will make sure not to give focus to the RadioButtons
 *  that are not selected in response to moving focus via the Tab key.
