/****************************************************************************
 * Project 2 for CS 1054 Fall 2003
 *  Quarterback Rating Calculator
 *
 *  File:          testQBRating.java
 *  Programmer:    Mir Farooq Ali
 *  Java Platform: JDK 1.4.2_01
 *  Compiler:      BlueJ - Version 1.3.0
 *  Last modified: October 1, 2003
 *
 *  Purpose:   This program takes input from a file named "qbstats.txt",
 *   which contains ten lines, each with the following information delimited
 *   with the | character:
 *    - Quarterback name
 *    - Yards
 *    - Attemps
 *    - Completions
 *    - Touchdowns
 *    - Interceptions
 *  The program prints out the quarterback ratings for each player by
 *  invoking methods from the QuarterbackRating class.
