Deprecate / delete this repo?

I can't get this project to compile and it hasn't been updated in years. Maybe it's a good idea to deprecate this repo or delete it in favor of [algolia/instantsearch-android-examples](https://github.com/algolia/instantsearch-android-examples). This one does compile and is maintained.

Even if you don't delete this repo, at least the readme should reference instantsearch-android-examples, because that was the one I actually needed.

Review the repository README and compare it with algolia/instantsearch-android-examples, the maintained replacement named in the issue. The work is done only after maintainers decide whether to deprecate or delete this repository; otherwise, update the README to point users to the replacement.
