  /**
   * Configures the specified component appropriate for the look and feel. This method is invoked
   * when the <code>ComponentUI</code> instance is being installed as the UI delegate on the
   * specified component. This method should completely configure the component for the look and
   * feel, including the following:
   *
   * <ol>
   *   <li>Install any default property values for color, fonts, borders, icons, opacity, etc. on
   *       the component. Whenever possible, property values initialized by the client program
   *       should <i>not</i> be overridden.
   *   <li>Install a <code>LayoutManager</code> on the component if necessary.
   *   <li>Create/add any required sub-components to the component.
   *   <li>Create/install event listeners on the component.
   *   <li>Create/install a <code>PropertyChangeListener</code> on the component in order to detect
   *       and respond to component property changes appropriately.
   *   <li>Install keyboard UI (mnemonics, traversal, etc.) on the component.
   *   <li>Initialize any appropriate instance data.
   * </ol>

   * @see #uninstallUI
