SupportSystem

/**
 * This class implements a technical support system. It is
 * the top-level class in this project. The support system
 * communicates via text input/output in the text terminal.
 * This class uses an object of class InputReader to read
 * input from the user and an object of class Responder to
 * generate responses.
 * It contains a loop that repeatedly reads input and
 * generates output until the user wants to leave.
