#
# 1) Ask the user their name.
# 2) Generate a random number between 1 and 20.
# 3) Give the user 5 guesses to guess the number.
# 4) If the user is wrong, tell them "high" or "low"
# 5) If they user is right, tell them they won and exit.
# 6) If they don't get the answer right in 5 tries, tell
#    them they lost and exit.
#
# EXTRA CREDIT
# 1) Save the win loss record of the player.
# Hint: save it in a flat text file.
# Hint: check out the stdlib "shelve"
# Hint: check out the "json" stdlib
# 2) Display the win loss record at the start of a game.
