* Making registration finer-grained so we only listen to the data we really need. * Moving the system listener registration to an external class (for testability and readability) * Adding a unit test (not yet complete) * Adding documention and cleaning up comments Still many things TODO: * Allow pausing of registrations * Add pause/resume to onPause/onResume of activities * Move sampling logic out of the hub * Optimize data reloading when display preferences change * (maybe) move the data hub and related classes to the "content" package
