/**
* Represents the group-header column template of the Grid which helps to customize the content of the group headers.
* To define the group header template, nest an `<ng-template>` tag with the `kendoGridGroupHeaderColumnTemplate`
* directive inside `<kendo-grid-column>`. ([See example](slug:grouping_grid_templates#toc-header-column-template)).
*
* The template context is set to the current data item and the following additional fields are passed:
* - `group`—The current group item.
* - `field`—The name of the field by which data is grouped.
* - `value`—The current group value.
* - `aggregates`—All 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>
* ```
