Added a fragment to our new user screen

Keeping with tradition, this fragment does not currently work.  There
seems to be an issue with the way the public class of TestDialog is
declared.... not sure why this is a problem...

I modified it from this code... once we get this working it should be
simple to add a button so the person can exit out...  Code from here:
