// Library class acts as interface between data files and storage / functions
//
// Assumptions:
// -- correctly formatted input from file
// -- each book item is uniquely identified by its srting criteria
// -- each command is uniquely and correctly identified by command char
// Implementation:
// -- holds a book factory, command factory, patron container, and bookcase
// -- Library reads input from data files
