# This code implements a Library application that lets user store and 
# retrieve books from a shelf. 
#
# Tasks: 
#  - Fix storeNewBook, and getBook
#  - Can you add a way to see all books in the library?
#  - Make a way to update a book?
#  - Make sure you cannot add a book with the same title (using compare?)
#

    # Look up the book in the library

    # Print out the book
