extend readme with sample code

[dutscher]

hi there,
it might be helpful to add this sample code to your readme.

it took me 30min to get the code working.
maybe other guys now need 1min 👍

please add to your readme:

package com.autostart;

import com.facebook.react.ReactActivity;

import com.ssg.autostart.AutostartPackage;
import com.facebook.react.ReactPackage;
import java.util.List;
import java.util.Arrays;

public class MainActivity extends ReactActivity {
  ...
  protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
      new AutostartPackage()
    );
  }
}

cheers and thanks for your module!
