/**
* We translate UUIDs in the import file into new UUIDs in the local instance for the following reasons:
* 1) Accidentally importing the same file twice cannot damage settings in an existing account.
* (Say, an account that was imported two months ago and has since had significant settings changes.)
* 2) All UUIDs used in the local instance will be generated with the same generator.
* 3) Importing a single file multiple times allows for creating multiple accounts from the same template.
* 4) Exporting an account and importing back into the same instance is a poor-man's account copy (until a real
* copy function is created, if ever)
