/**
 * Created by Allan Wang on 2017-08-01.
 *
 * Base activity for any activity that would have extended [AppCompatActivity]
 *
 * Ensures that some singleton methods are called.
 * This is simply a convenience class;
 * you can always copy and paste this to your own class.
 *
 * This also implements [CoroutineScope] that adheres to the activity lifecycle.
 * Note that by default, [SupervisorJob] is used, to avoid exceptions in one child from affecting that of another.
 * The default job can be overridden within [defaultJob]
