  /**
   * The `MPAdConversionTracker` class provides a mechanism for reporting application download
   * (conversion) events to MoPub. This type of tracking is important for measuring the effectiveness
   * of cross-promotional and direct-sold advertising.
   *
   * To track application downloads, get a reference to the shared instance of this class using the
   * `sharedConversionTracker` method. Then, in your application delegate's
   * `application:didFinishLaunchingWithOptions:` method, call the
   * `reportApplicationOpenForApplicationID:` method on the shared instance. With this call in place,
   * the conversion tracker will report an event to MoPub whenever the application is launched on a
   * given device for the first time. Any subsequent launches will not be recorded as conversion
   * events.

   * Notifies MoPub that a conversion event should be recorded for the application corresponding to

   * A conversion event will only be reported once per application download, even if this method
   * is called multiple times.
   *
   * @param appID An iTunes application ID.
   *
   * The easiest way to find the correct ID for your application is to generate an iTunes URL using
   * the [iTunes Link Maker](https://itunes.apple.com/linkmaker), and then extract the number
   * immediately following the "id" string.
   *
   *     For example, the iTunes URL for the "Find My Friends" application is
   *     https://itunes.apple.com/us/app/find-my-friends/id466122094, so its application ID is
   *     466122094.
