cube is a dependency for earthdistance and it's gotten some light
advocacy throughout the years as the 'way to do it'.  I tried it
myself way back in the day and concluded a while back that the 'box'
type + gist was better than earthdistance for bounding box operations
-- it just seemed easier to understand and use.  If you search the
archives you'll probably find a couple of examples of me suggesting as
such.
