/* CSCI 200: Assignment 1 (Rock Paper Scissors): Tyler Beckman
*
* Author: Tyler Beckman
* Resources used:
* While learning how to use classes & polymorphism in the way I wanted to,
* student Maxwell Gross helped me debug why the way I was trying to use classes
* didn't work (virtual fields not existing, where I needed to put class
* definitions vs method definitions, etc). No code was copied or written for
* me, he just helped me understand how all of these structures I was used to in
* other langs like Java and JS worked in cpp :)
*
* Description:
* A C++ program to play rock paper scissors (lizard spock) against
* randomly-generated computer hands. A hand can be entered to start, and is
* then compared against a random one. The game can then be played again until
* the user chooses to stop. After each round, statistics are gathered and
* displayed after the user chooses to exit the game.
*
* Note on project structure:
* Just for fun and to get ahead on learning cpp, I did create my RPS using
* classes, inheritance, and polymorphism. I have experience with this in
* multiple other languages, so I felt it would be fun to use this as an excuse
* to learn how the concepts work in cpp. I apologize if this is more
* complicated than we were supposed to make it, but it was fun and it should
* still be a perfectly functional and point-scoring program :). To clarify, I
* didn't copy any code but I did use multiple online tutorials and references
* to learn how classes and the such work in cpp.
