/*
 *  bookFactory.h
 *  Authors: Camron Staley, Jessica Chann, Alex Christensen, KJ
 *
 *  Class that represents a factory by using hashing to generate
 *  different product types
 *
 *  Features:
 *  -- allows library system to create any subclass of type product
 *  -- subclasses currently include books
 *  -- book subclasses currently include fiction, youth, non-fiction
 *
 *  Implementation and Assumptions:
 *  -- size defaults to number of capital ascii characters
 *  -- size should be changed when you add more subclasses
 *  -- hashing uses the type of book in a string
 *  -- string type should be unique to each product type
 *
 *  Limitations:
