function FilterPluginBase::convertExposedInput

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 chosen 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 chosen in the checkboxes.
