In our next practice session, we need to build a class that will automatically translate a number into its roman numeral counterpart. As with the previous episode, we'll use TDD and PHPSpec to drive this process.
Homework: what would happen if the user passed 0 to our converter? Shouldn't we take exception to that? On your own, implement this functionality using TDD.
