TJStoreReviewController is a simple wrapper around SKStoreReviewController that provides the following.

• It's safe to call into on versions of iOS prior to 10.3.
• It has simple throttling based on how long the app has been installed.
• It has a helpful method for presenting store review UI in the App Store (for use when users manually tap a "Rate this app" button, for example), which defers the automatic prompt from showing.

tl;dr -- Step #2 is the only necessary one!

1. On app launch, you can optionally call the +appDidLaunch. This doesn't trigger any prompt showing, but it marks the first time the app was launched to better inform TJStoreReviewController of when to show the prompt next. If you don't call +appDidLaunch the first time +requestThrottledReview will be treated as the initial app launch, which is often good enough.
2. In situations where you think it would be good to optimistically show a store prompt, call +requestThrottledReview. That's it!
3. If your app includes a dedicated button to allow users to review your app you can call +reviewInAppStore: passing your app's iTunes identifier. This shows the rating UI for your app in the App Store and also defers the next time + requestThrottledReview will trigger the prompt to be shown.
