 * A cell editor that manages a checkbox.

 * This class may be instantiated; it is not intended to be subclassed.

 * Note that this implementation simply fakes it and does does not create
 * any new controls. The mere activation of this editor means that the value
 * of the check box is being toggled by the end users; the listener method
 * <code>applyEditorValue</code> is immediately called to signal the change.
