Making the Where am I? App Part I

Today I made the first part of the Where am I app. So far, I've gotten it to get the current latitude, longitude, and altitude, however I haven't gotten the time to test it. I did this by creating a LocationManager, then creating a Location that is found by calling the LocationManager's getLastKnownLocation method. From there, I can determine the Location's latitude, longitude, and altitude. Hopefully, I'll be able to use these to eventually determine the location of the user, and put this into a text box that will display it.
