Mirror the ISO 3166 country / province databases including IDs
The country/province lists do not have the correct ISO 3166 numeric ids (ex 1228 for USA should be 240).
This is important because everyone else uses ISO ids and in order to map the right country IDs for CiviCRM, you need to create a mapping table.
As well not all of the country names match.
Why not just use the ISO data dumps to create these tables?
This becomes very important when you need to create forms with addresses in them. You have to use one ID for civi and the standard ID for everything else....
