US data for the suburbs table: zip codes with latitude and longitude, some YML and some CSV

All zip codes for the US = the complete dataset: suburbs-US_zip_codes_states-orig-all.*
Smaller files were made by somewhat randomly picking from the complete dataset.
...600items.yml = 600 entries from the complete data set (see the header comment in the file)
...227items.yml = a subset of the '...600entries.yml' file (see the header comment in the file)
...tiny_7_items.csv = 7 entries from the complete data set
