 * Create and return an instance of the Whoops runner.

 * container of your choice. This service depends on two others:
 *
 * - 'config' (which should return an array or array-like object with a "whoops"
 *   key, containing the configuration for whoops).
 * - 'Mezzio\WhoopsPageHandler', which should return a
 *   Whoops\Handler\PrettyPageHandler instance to register on the whoops
 *   instance.
 *
 * The whoops configuration can contain:
 *
 * <code>
 * 'whoops' => [
 *     'json_exceptions' => [
 *         'display'    => true,
 *         'show_trace' => true,
 *         'ajax_only'  => true,
 *     ]
 * ]
 * </code>

 * All values are booleans; omission of any implies boolean false.
