Project 0 - Interpreter

This project is optional and will NOT be graded. Project 0 is intended to serve as a quick review of Java, a gentle introduction to the first few concepts in the textbook, and a handy testcase for students to try out the electronic submission and automated grading environments.

Due date: Please turn in (if you wish to turn it in) at the beginning of your first PSO session, in week 2 of the course.
