Verifies the first launch of an app installed as a result of an ad.

Apps that participate in an advertising network should call
register when the app first launches.
This method generates a conversion notification, which is the cryptographically signed data validating that a user installed and launched this app as a result of an ad.
The first call to
register generates the notification if the device has attribution data for that app; subsequent calls have no effect.
