An enumeration denoting the authorization status of a script.
The user needs to authorize this script to use one or more services. In most cases, the script
prompts the user for authorization the next time it runs; however, if the script is published
as an add-on that uses installable triggers, the trigger runs the
script without prompting for authorization but throws an exception if the script attempts to
call the unauthorized service.
The user has granted this script all the authorization it currently requires.
