/**
* Represents the group-header cell template of the Grid which helps to customize the content of the group header item.
* To define the group header template, nest an `<ng-template>` tag with the `kendoGridGroupHeaderTemplate`
* directive inside `<kendo-grid-column>`. ([See example](slug:grouping_grid_templates#toc-header-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.
* - `index`—The index of the current group.
* - `expanded`—A boolean value indicating if the group is currently expanded.
*
* @example
* ```html
* <kendo-grid [data]="gridData" [group]="groups">
* <kendo-grid-column field="ProductName">
* <ng-template kendoGridGroupHeaderTemplate let-group let-field="field" let-value="value">
* <strong>{{field}}</strong>: {{value}}
* </ng-template>
* </kendo-grid-column>
* </kendo-grid>
* ```
