/**
 * The {@code CheckboxGroup} class is used to group together
 * a set of {@code Checkbox} buttons.
 * <p>
 * Exactly one check box button in a {@code CheckboxGroup} can
 * be in the "on" state at any given time. Pushing any
 * button sets its state to "on" and forces any other button that
 * is in the "on" state into the "off" state.
 * <p>
 * The following code example produces a new check box group,
 * with three check boxes:
 *
 * <hr><blockquote><pre>
 * setLayout(new GridLayout(3, 1));
 * CheckboxGroup cbg = new CheckboxGroup();
 * add(new Checkbox("one", cbg, true));
 * add(new Checkbox("two", cbg, false));
 * add(new Checkbox("three", cbg, false));
 * </pre></blockquote><hr>
 * <p>
 * This image depicts the check box group created by this example:
 * <p>
 * <img src="doc-files/CheckboxGroup-1.gif"
 * alt="Shows three checkboxes, arranged vertically, labeled one, two, and three. Checkbox one is in the on state."
