             * You have two options for updating your notification (this class uses approach #2):
             *
             *  1. Use a new NotificationCompatBuilder to create the Notification. This approach
             *  requires you to get *ALL* the information that existed in the previous
             *  Notification (and updates) and pass it to the builder. This is the approach used in
             *  the MainActivity.
             *
             *  2. Use the original NotificationCompatBuilder to create the Notification. This
             *  approach requires you to store a reference to the original builder. The benefit is
             *  you only need the new/updated information. In our case, the reply from the user
             *  which we already have here.
             *
             *  IMPORTANT NOTE: You shouldn't save/modify the resulting Notification object using
             *  its member variables and/or legacy APIs. If you want to retain anything from update
             *  to update, retain the Builder as option 2 outlines.
