Transform the input from a grouped filter into a standard filter.
When a filter is a group, find the set of operator and values that the choosen item represents, and inform views that a normal filter was submitted by telling the operator and the value selected.
The param $selected_group_id is only passed when the filter uses the checkboxes widget, and this function will be called for each item choosen in the checkboxes.
