Sort countries by country, not by ID
more fixes
Data map fixes
Make sure datamap is restored prior to returning counts or array values extracted from internal values
data() method returns keys and values as array, not just the values with auto incrmenting integer key.
Country list sort order
Countries list is returned sorted by country name, as in prior release.  Optional parameter available if caller needs country list sorted by country id.
