views_handler_relationship_groupwise_max::left_query in handlers/views_handler_relationship_groupwise_max.inc

Generate a subquery given the user options, as set in the options. These are passed in rather than picked up from the object because we generate the subquery when the options are saved, rather than when the view is run. This saves considerable time.
