8   * Handles "facets_filter" event and triggers "facets_filtering".
9   *
10   * The facets module will listend and trigger defined events on elements with
11   * class: "js-facets-widget".
12   *
13   * Events are doing following:
14   * "facets_filter" - widget should trigger this event.
15   * "facets_filtering" - The facets module will trigger this event before
16   *   filter is executed.
17   *
18   * This is an example how to trigger "facets_filter" event for your widget:
19   *   $(once('my-custom-widget-on-change', '.my-custom-widget.js-facets-widget'))
20   *     .on('change', function () {
21   *       // In this example $(this).val() will provide needed URL.
22   *       $(this).trigger('facets_filter', [ $(this).val(), false ]);
23   *     });
24   *
25   * The facets module will trigger "facets_filtering" before filter is
26   * executed. Widgets can listen on "facets_filtering" event and react before
27   * filter is executed. Most common use case is to disable widget. When you
28   * disable widget, a user will not be able to trigger new "facets_filter"
29   * event before initial filter request is finished.
30   *
31   * This is an example how to handle "facets_filtering":
32   *   $(once('my-custom-widget-on-facets-filtering', '.my-custom-widget.js-facets-widget'))
33   *     .on('facets_filtering.my_widget_module', function () {
34   *       // Let's say, that widget can be simply disabled (fe. select).
35   *       $(this).prop('disabled', true);
36   *     });
37   *
38   * You should namespace events for your module widgets. With namespaced events
39   * you have better control on your handlers and if it's needed, you can easier
40   * register/deregister them.
