This project is discussed in chapters 5 and 12.

This project implements a technical support system for customers of the 
DodgySoft software company. Users can describe their software problems and 
get advice instantly!

The idea is based on Eliza - a famous program described by Joseph Weizenbaum 
in 1966. (Do a web search for "Eliza" and "Weizenbaum" if you want to know 
more about this.)

In fact, it is much more primitive than Eliza. But that's enough to match the 
quality of many software companies' technical support advice...  ;-)

To start this program, create a SupportSystem object and execute the "start" 
method.

Then start describing your problem by typing in the terminal window.

The purpose of this project is to demonstrate and study library classes, such 
as ArrayList, HashMap, HashSet, and Random.
