/*
* Author: Michael Kolling
* Version: 1.0
* Date: July 1999
*
* This class is part of Zork. Zork is a simple, text based adventure game.
*
* This parser reads user input and tries to interpret it as a "Zork"
* 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.
