/* Grades.java computes letter grades using the "curve" method.
 *
 * Begun by: Charles Hoot for Hands on Java.
 * Adapted from code by: Adams, Fall 1995, Hands on C++.
 * Completed by:
 *
 * Input(keyboard): a sequence of names and scores.
 * Output: the sequence of names with corresponding letter grades,
 *          based on the "curve" method of grading.
