Hh refactor

Hi Joe,

Very nice work!  I made a few edits on this branch that fell into the following categories:

* **Style / convention stuff.** Whitespace, indentation, giving variables & methods descriptive names.
* **Refactoring into methods.** Take a look at what I did there and let me know if you have questions.

Lastly, as we talked about yesterday, it might be a good idea to have a single data structure with team name, number of wins, & number of losses, instead of 3 separate ones.  But the way you did it works just fine, too.

Nice job!

Helen
