SQLite finally working!

So it took longer than I had hoped, but I finally got the framework for SQLite up and running in my app. You can now add the athlete to the database in the timing activity, and it will show up when you navigate to the results activity. Now that this is working, I am going to work on getting the athletes' times stored correctly for each event and having an easy way to recall this info. I'm not sure if I'll have time to do this in the next week with my other project but I hope to get this and more features done in RunningTally in the remaining weeks of summer.
