Due to this repo getting some usage, we have decided to move this to a more official repo under the Firebase organization here: https://github.com/firebase/Firebase-Unity
You can see the announcement blog here: https://www.firebase.com/blog/2015-12-18-firebase-unity.html
Please switch to the new repo as soon as you can. I will continue to mirror this repo for a while longer, but we will be more closely monitor usage and issues on the "official" repo.
Thanks for using Firebase and your feedback!
