Summary

This branch will deprecate SDLRouterService and SDLBroadcastReceiver and create BaseRouterService and BaseBroadcastReceiver which extend these deprecated classes. This is because there is a lot of confusion added by the creating a SDLRouterService class in the application which uses the same name as its parent class.
