This represents the core of the project, as most of the work left will be in perfecting the web-based user interface and creating test cases to ensure that the program is correct. We have also begun to formulate and work on other test cases for the project to run on.
Work is underway on a stack class.
We briefly discussed but later dismissed the idea of using a matrix, since it is not naturally structured for the tester. In other words, there really aren't many good axioms that would help to fully exercise the tester.
