Functions:

  Lets users set alerts or alarms based on these stops
  App will alert user if app is running and in foreground by a Green alert bar on top of view and a Pop up alert button.
 App also alerts user when running but in background by a custom notification in notification centre, the user must dismiss or touch this alert to stop the custom sound playing.
  App will also notify user if the app is not running due to region monitoring, it will then use the notification alert as if the app was not running.
