== Notes ==
* The value of the <code>userOptOut</code> state is persisted across application launches on the shared preferences object local to the App SDK.
* The Opt-Out status is internally managed and stored by the SDK. The App does not need to retain the value of SDK Opt-Out status.
* The SDK will continue measurement even after the user has opted out from Nielsen measurement.
