Refactoring shipping and beginning to explore customs workings.
Added customs inputs to admin order grid.  Beginning to create install and resource files for maintaining this data in the db.
Finally figured out how to get paginated images parsed and saved to the DB for international shipping labels.
UPS international invoice functional. I do not know if it is correct.
Handling some diacritics fails for UPS labels.  Also correcting a bug in setting customer name as company name.
Working towards admin seletion of carrier services.
Can specify USPS add ons on the admin side.
USPS First Class International rates are described as "USPS Standard Mail."  That is really confusing.
