Once the stats provider work is committed, this demonstrates it

Good thing I re-reviewed this one, my git command was 'git commit -a' but that doesn't hoover up new files so it was missing two. I re-pushed with all files and using the new read-only permission. Functionality is the same though

1. The stats provider PR still does not provide an API in the sense that the main add content API does, wrapping up all this content provider and cursor stuff into more user friendly functions. Adding the contract file was the minimum requirement for merging the provider, but adding a high level API was desired, and would be the minimum requirement for merging anything into this apisample project.

2. This feels tacked onto the UI like an after thought. I think you need a navigation drawer to switch between the different activities.
