Kai's changes and comments

Naomi!
I like where this is going overall. It's well-structured, modular, and dry. You make good use of methods and classes to accomplish a series of small tasks that lead to your overall goal. Super awesome :)

I really like the idea of having a verify class method. Again, great structure. However, as implemented here, they don't actually do what you intend. I would really think about what they should be verifying and try rewriting them to get the desired result. 

Also--I had to make a number of changes to get the app to run. Make sure you always try running your code and work through all the kinks before submitting it! Be sure to look through all of the changes I made and my comments about why I made them. Let me know if you have any questions!
