/**
 * Represents the group-header column template of the Grid, allowing customization of group header content.
 * To define the group header template, nest an `<ng-template>` tag with the `kendoGridGroupHeaderColumnTemplate`
 * directive inside a `<kendo-grid-column>`. [See example](https://www.telerik.com/kendo-angular-ui/components/grid/grouping/templates#header-column-template).
 *
 * The template context is set to the current data item and provides the following fields:
 * - `group`&mdash;The current group item.
 * - `field`&mdash;The name of the field used for grouping.
 * - `value`&mdash;The current group value.
 * - `aggregates`&mdash;Aggregate values for the current group.
 *
 * @example
 * ```html
 * <kendo-grid-column field="ProductName" title="Product Name">
 *     <ng-template kendoGridGroupHeaderColumnTemplate let-group="group" let-aggregates="aggregates">
 *         <span title="Group Header Column Template for ProductName">
 *             Count: {{ aggregates.Discontinued.count }}
 *         </span>
 *     </ng-template>
 * </kendo-grid-column>
 * ```
