          COMP 5690: Senior Computer Science Project. From June - August 2023 this project was funded by a student research 
          grant (awarded to Michael Myer) conferred by the Faculty of Science and Technology at Mount Royal University. 
          Starting September 2023 this project is funded by a Provost's Teaching-Learning Enhancement Grant (TLEG).
