This is the proper way to pass information BACK to a calling activity with what happened in the child activity.
Currently we use a global variable, but then need to add a bunch of logic in the parent activity to know if we're starting from scratch, or coming back from settings.
Using this means it's cleaner and we have a special Interface that's called upon return that we can check if we need to reload data, and then do so. The onCreate is NOT called again.
