/*
 * highscore
 *
 * A module that keeps track of your highscores
 *     even after you close your program
 *
 * -It automatically keeps only the top 10
 * -To add an entry, do highscore.add ("name", 999)
 * -To get the entry at location n, (from 1 to 10), do
 *     highscore.getname (n)
 * -To get the score at location n, (from 1 to 10), do
 *     highscore.getscore (n)
 * -The highscores are recorded in file "highscores.dat"
