Correct, reproducible, fast builds - now for Xcode

Tulsi integrates Bazel (Google's build tool) with Apple's Xcode IDE. Tulsi is currently in Beta but is broadly used within Google.

Tulsi is in Beta. There are still some functional limitations, but we believe that Tulsi is stable enough for production use. The Tulsi team monitors and responds actively to bug reports from users.
