public class Parser
extends java.lang.Object

This class is the main class of the "World of Zuul" application. "World of Zuul" is a very simple, text based adventure game. This parser reads user input and tries to interpret it as an "Adventure" command. Every time it is called it reads a line from the terminal and tries to interpret the line as a two word command. It returns the command as an object of class Command. The parser has a set of known command words. It checks user input against the known commands, and if the input is not one of the known commands, it returns a command object that is marked as an unknown command.
