 * At the appropriate time,

 * <P>
 * This method first looks up the {@code ActionMap} from the

 * invoking {@code createAudioAction()} to create an {@code
 * Action} for each element.  The resulting {@code Action} is
 * placed in the {@code ActionMapUIResource}, using the array
 * element as the key.  For example, if the {@code

 * <p>
 * If the value of the default {@code "AuditoryCues.actionMap"} is

/**
 * Returns an <code>ActionMap</code> containing the audio actions
 * for this look and feel.
 * <P>
 * The returned <code>ActionMap</code> contains <code>Actions</code> that
 * embody the ability to render an auditory cue. These auditory
 * cues map onto user and system activities that may be useful
 * for an end user to know about (such as a dialog box appearing).
 * <P>
 * At the appropriate time,
 * the {@code ComponentUI} is responsible for obtaining an
 * <code>Action</code> out of the <code>ActionMap</code> and passing
 * it to <code>playSound</code>.
 * <P>
 * This method first looks up the {@code ActionMap} from the
 * defaults using the key {@code "AuditoryCues.actionMap"}.
 * <p>
 * If the value is {@code non-null}, it is returned. If the value
 * of the default {@code "AuditoryCues.actionMap"} is {@code null}
 * and the value of the default {@code "AuditoryCues.cueList"} is
 * {@code non-null}, an {@code ActionMapUIResource} is created and
 * populated. Population is done by iterating over each of the
 * elements of the {@code "AuditoryCues.cueList"} array, and
 * invoking {@code createAudioAction()} to create an {@code
 * Action} for each element.  The resulting {@code Action} is
 * placed in the {@code ActionMapUIResource}, using the array
 * element as the key.  For example, if the {@code
 * "AuditoryCues.cueList"} array contains a single-element, {@code
 * "audioKey"}, the {@code ActionMapUIResource} is created, then
 * populated by way of {@code actionMap.put(cueList[0],
 * createAudioAction(cueList[0]))}.
 * <p>
 * If the value of the default {@code "AuditoryCues.actionMap"} is
 * {@code null} and the value of the default
 * {@code "AuditoryCues.cueList"} is {@code null}, an empty
 * {@code ActionMapUIResource} is created.
 *
 *
 * @return      an ActionMap containing {@code Actions}

 * @throws ClassCastException if the value of the
 *         default {@code "AuditoryCues.actionMap"} is not an
 *         {@code ActionMap}, or the value of the default
