/**
 * @file nodequeue.views.inc
 * Provides support for the Views module.
 *
 * This implementation is almost entirely based around a relationship
 * which is stapled to the 'node' table via hook_views_data_alter.
 *
 * The relationship allows you to define 0 or more queues that join the
 * queue tables, limiting the join to just the queues selected. Once
 * the queues are joined in, the queue fields will show up, and they
 * have the usual array of arguments, sorts, fields and filters; since
 * the real legwork is done by the relationship, most of these are
 * really quite simple.
