begin the modification to use a spinner instead of being hard coded.
I will be keeping Quiz as a 0..N array and then to make sure that the
ProblemActivity class follows that also.
I have added a rule where the constructor will return null if the 
problems are less than 1.
Added 0 so that I can save it for later.
Updated so that I will have a good consise version of the master branch.
I also removed files that are no longer needed.
