Returns whether a party/raid member is nearby. The range check used by this function isn't directly based on the player's abilities (which may have varying ranges); it's fixed by Blizzard at a distance of around 40 yards (which encompasses many common healing spells and other abilities often used on raid members).
Also returns nil for units outside the player's area of view.
