Set up classes for Library: Book, Library, User
Added methods to Book class: initialize(author, title), add_description, get_info
Initialize user class object with @name and @checked_out_books instance variables.
Require name when initializing new user.
Add working 'check_out' method to Library class for checking out books.
Add working 'check_in' method for checking books back in.
Add complexity to Library methods: check_out (checks for number of books the user has checked out, updates book with check out date, adds book to list of checked out books), check_in (checks book status before checking in, updates status, dates, list of checked out books). Added functionality to list_books (lists books in library with status), added working methods list_checked_out, list_overdue (lists checked out and overdue books respectively).
Add minimal documentation to all classes and methods.
7:18pm on Friday, commit for end of day assignment status
