Tennis Refactoring Kata

Work on the Tennis Refactoring Kata by Emily Bache.

Clean-up the code in the class TennisGame1 to a point where someone can read it and understand it with ease. After working on TennisGame1 you can clean-up the code in one of the other classes.

To work on this assignment get a local copy of the repository (clone, or fork and then clone) and open the java folder from IntelliJ. To build and run the tests you can either: follow the instructions in the README.md file; invoke the "verify" lifecycle from the IntelliJ Maven panel; right click on the TennisTest class in IntelliJ and then choose Run 'TennisTest' from the menu.
