/**
* Sort represents information relevant to sorting.
*
* When data needs to be sorted according to one or several attributes,
* we can use Sort to represent the sorting information and generate
* appropriate hyperlinks that can lead to sort actions.
*
* A typical usage example is as follows,
*
* ```php
* public function actionIndex()
* {
* $sort = new Sort([
* 'attributes' => [
* 'age',
* 'name' => [
* 'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],
* 'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],
* 'default' => SORT_DESC,
* 'label' => 'Name',
* ],
* ],
* ]);
*
* $models = Article::find()
* ->where(['status' => 1])
* ->orderBy($sort->orders)
* ->all();
*
* return $this->render('index', [
* 'models' => $models,
* 'sort' => $sort,
* ]);
* }
* ```
*
* View:
*
* ```php
* // display links leading to sort actions
* echo $sort->link('name') . ' | ' . $sort->link('age');
*
* foreach ($models as $model) {
* // display $model here
* }
* ```
*
* In the above, we declare two [[attributes]] that support sorting: `name` and `age`.
* We pass the sort information to the Article query so that the query results are
* sorted by the orders specified by the Sort object. In the view, we show two hyperlinks
* that can lead to pages with the data sorted by the corresponding attributes.
*
* For more details and usage information on Sort, see the [guide article on sorting](guide:output-sorting).
*
* @property array $attributeOrders Sort directions indexed by attribute names. Sort direction can be either
* `SORT_ASC` for ascending order or `SORT_DESC` for descending order. Note that the type of this property
* differs in getter and setter. See [[getAttributeOrders()]] and [[setAttributeOrders()]] for details.
* @property-read array $orders The columns (keys) and their corresponding sort directions (values). This can
* be passed to [[\yii\db\Query::orderBy()]] to construct a DB query.

* - The `default` element specifies by which direction the attribute should be sorted
* if it is not currently sorted (the default value is ascending order).
* - The `label` element specifies what label should be used when calling [[link()]] to create
* a sort link. If not set, [[Inflector::camel2words()]] will be called to get a label.
* Note that it will not be HTML-encoded.
*
* Note that if the Sort object is already created, you can only use the full format
