Assisted Inject autowiring

Hey guys,

I'd like to dig-up [this](https://groups.google.com/forum/#!topic/google-guice-dev/FYWtMR9G31E) old issue.

I've attached some code we have in production now relating to assisted inject. Its a neat feature that we're using extensively, and would really like to continue using, without expanding our current configuration stuff any more.

What I would really like is for guice to auto discover factories. Its become convention on our class to simply put the factory interface above the constructor, so we have many classes like this:

``` Java
public class SomeController{

public interface Factory{
public SomeController create(List parentList);
}

@Inject
public SomeController(EventBus eventBus, OtherCoolServices services, @Assisted List parentList){
this.thing = //...
}

//...
}
```

the problem is that when we add a factory, we have to find out which flow is using that factory and make sure the modules are updated --probably the typical reason for auto-wiring over explicit configuration.

So yeah, please make this happen!
