 || '''get_absolute(self, points)''' || Given a list (or array) of Points geo-referenced to this '''Geo_reference''', return a list (or array) of Points with absolute coordinates (ie, relative to the UTM origin).  Note: also changes the input Point list! The inverse of '''get_relative()'''. ||

If either instance (but not both) have a '''.zone''' of DEFAULT_ZONE then copy the '''.zone''' attribute fron the instance with a real zone.
