Compatibility with other annotation processing libraries

[izumin5210]

When I use Droidux with Dagger 2, the compiler throws following:

Execution failed for task ':app:compileDebugJavaWithJavac'.
> java.lang.IllegalArgumentException: DroiduxRootStore cannot be represented as a Class<?>.

New store generation plan

User define:

@Reducer(Counter.class)
public class CounterReducer {
  @Dispatchable
  Counter increment(Counter counter, IncrementCounterAction action) {
    // ...
  }
}

@Store({CounterReducer.class})
public interface RootStore extends Store {
  Counter counter();
  Observable<Counter> observableCounter();
}

Processor generate:

public class DroiduxRootStore implements RootStore {
  public Counter counter() {
    // ...
  }

  public Observable<Counter> observeCounter() {
    // ...
  }

  public Observable<Action> dispatch(Action action) {
    // ...
  }
}
