 * Homework 1 -- Implement a DFA
 * Filename: driverDFA.java
 * Student Name: Eric Stenton
 * Due Date: March 11, 2020
 * Version 1.0
 *
 * This file contains the main function for implementing a DFA to solve the man,
 * wolf, goat, and cabbage riddle. It reads a single string of input from
 * the command line and processes it using the ManWolf class to determine if
 * string leads to an acceptance state or not.
