/**
 * A simple output system for beginning programmers.  Permits 
 * writing of basic data types without delving into the workings 
 * of the various Java libraries.  Using this library makes it
 * easier to change programs to do output to a file (hopefully) and
 * for students to extend the class by adding new routines.
 * <p>
 * While it would be preferable to have this class extend 
 * PrintWriter, this makes it difficult to make it work with files
 * (at least in my experience).
 * <p>
 * Note that this class does not precisely match the description
 * in the text.  The one described in the text is designed to be
 * somewhat more understandable for beginning programmers.  
 * <p>
 * Requires Java 1.1 or later.
