-- To retrieve a list of supported geo locations, send a 'GET' request to
-- the '2013-04-01\/geolocations' resource. The response to this request
-- includes a 'GeoLocationDetailsList' element with zero, one, or multiple
-- 'GeoLocationDetails' child elements. The list is sorted by country code,
-- and then subdivision code, followed by continents at the end of the
-- list.
--
-- By default, the list of geo locations is displayed on a single page. You
-- can control the length of the page that is displayed by using the
-- 'MaxItems' parameter. If the list is truncated, 'IsTruncated' will be
-- set to /true/ and a combination of
-- 'NextContinentCode, NextCountryCode, NextSubdivisionCode' will be
-- populated. You can pass these as parameters to
-- 'StartContinentCode, StartCountryCode, StartSubdivisionCode' to control
-- the geo location that the list begins with.
