// Class: COP 2931

// Description: This program simulates the checking out and checking in of books
// from a library.  Book data and library card data is read in from books.txt
// and cards.txt and stored in separate arrays of their respective object types.
// When the program user is finished making changes to the database, the
// existing text files are deleted and new ones are created to reflect all
// changes made.
