 /**
  * The autocomplete callback function for the Linkit Entity plugin.
  *
  * @return
  *   An associative array whose values are an
  *   associative array containing:
  *   - title: A string to use as the search result label.
  *   - description: (optional) A string with additional information about the
  *     result item.
  *   - path: The URL to the item.
  *   - group: (optional) A string with the group name for the result item.
  *     Best practice is to use the plugin name as group name.
  *   - addClass: (optional) A string with classes to add to the result row.
