// This is a super simplified example of how to use the new dagger.android framework

// read https://proandroiddev.com/how-to-android-dagger-2-10-2-11-butterknife-mvp-part-1-eb0f6b970fd

// For a complete codebase using dagger.android 2.11-2.17, butterknife 8.7-8.8, and MVP,
// see https://github.com/vestrel00/android-dagger-butterknife-mvp

// This example works with Dagger 2.11-2.17. Starting with Dagger 2.11, 
// @ContributesAndroidInjector was introduced removing the need to define @Subcomponent classes.
