 - a `spawn` method that launches the program in an interactive mode. It returns an `Agent` object with and `act` method that takes a sequence of input strings and returns a list of strings printed to `stdout` in response.
 - a `test` method that takes a list of test cases. A test case is a tuple of 2 lists: the first list is the input strings, the second is the expected output strings. The method returns a full log of all test runs and updates `program.avg_score` and `program.test_pass_rate` attributes.
