     * @ngdoc directive
     * @name mdtRow
     * @restrict E
     * @requires mdtTable
     *
     * @description
     * Representing a row which should be placed inside `mdt-table` element directive.
     *
     * <i>Please note the following: This element has limited functionality. It cannot listen on data changes that happens outside of the
     * component. E.g.: if you provide an ng-repeat to generate your data rows for the table, using this directive,
     * it won't work well if this data will change. Since the way how transclusions work, it's (with my best
     * knowledge) an impossible task to solve at the moment. If you intend to use dynamic data rows, it's still
     * possible with using mdtRow attribute of mdtTable.</i>
     *
     * @param {string|integer=} tableRowId when set table will have a uniqe id. In case of deleting a row will give
     *      back this id.
     *
     * @example
     * <pre>
     *  <mdt-table>
     *      <mdt-header-row>
     *          <mdt-column>Product name</mdt-column>
     *          <mdt-column>Price</mdt-column>
     *      </mdt-header-row>
     *
     *      <mdt-row
     *          ng-repeat="product in products"
     *          table-row-id="{{product.id}}">
     *          <mdt-cell>{{product.name}}</mdt-cell>
     *          <mdt-cell>{{product.price}}</mdt-cell>
     *      </mdt-row>
     *  </mdt-table>
     * </pre>
