Callback fired when the user attempts to group or ungroup the listGrid, or when

void onGroupBy(GroupByEvent event)
groupBy() is called programmatically. This event may be cancelled.
This notification is fired before the data is updated
to reflect the grouping. See also ListGrid.groupByComplete().
Note that this method is not called when the data is regrouped, either programmatically, or in response to new data arriving from the
server, and such regrouping can't be canceled - instead use callback ListGrid.regroup().
