/*
 *  book.h
 *  Authors: Camron Staley, Jessica Chann, Alex Christensen, KJ
 *
 *  This class is the representation of a book in a library with
 *  basic data members.
 *
 *  Features:
 *  -- Output the type of product and basic information about it.
 *  -- Has getters to get product type and number of products.
 *  -- Tracks the number in stock 
    -- Tracks the number checked out
 *
 *  Implementation and Assumptions:
 *  -- Creates a product to add to the library.
    -- pure virtual create printheader, print, printpartial
    setData, partial set data, ==, and <
 *
 *  Limitations:
 *  -- Data about the book is restricted to the data members I created.
 *  -- Can only get information about the book, create new books,
 *     and initalize book data
