Use libraries for clean generated code

Created by: ziem

It is just another suggestion from me.

Developers should consider using following libraries for cleaner code:

• Retrofit - A type-safe REST client for Android and Java
• RxJava - Reactive Extensions for the JVM
• FragmentArgs - Annotation Processor for setting arguments in android fragments
• Parceler - Android Parcelables made easy through code generation
• ButterKnife - View "injection" library for Android
• Timber - logger with a small, extensible API which provides utility on top of Android's normal Log class.
• StorIO/cupboard - ORM/persistence
• Nucleus/Mosby - MVP

Instead of writing N lines of code we can simply use annotations and let annotation processors do the rest for us.
