Integrate Dagger2 for the love of dependency injection and less boilerplate code

I would understand if you guys had plans to involve Dagger some point in near future as it was a beginning but my experience tells me that earlier is even better.

Dagger make it easy to create reusable, interchangeable modules, offers better resource sharing and facilitates testable code. I can help in kicking-off with it. It will provide the support on which team can build a stable and scalable product.
