Library System
Learn about class methods and class variables by implementing a simplified library system.
Problem
Implement a simplified library system that supports the following functionality:
Initially, the librarian can import book records into the system via a
CSVfile.Members of the library can borrow and return books.
Format of the CSV file
Other than the first line (header), each row in the CSV file has a comma-separated list of the book titles and the authors.

Example use of the library system
# Importing the books from a CSV fileLibrary.import_books(File.join(File.dirname(__FILE__), "files","books.csv"))puts "Number of books: #{Library.book_count}" # => Number of books: 10# Adding new membersjohn = Member.new("John Sully", "1001")mike = Member.new("Mike Zasky", "1002")book = Library.find_by_title("Name of the Fourth Book")Library.borrow(john, book)# Output: "John Sully borrowed 'Name of the Fourth Book'"Library.borrow(mike, book)# Output: The book 'Name of the Fourth Book' is not available!Library.return(book)Library.borrow(mike, book)# Output: "Mike Zasky borrowed 'Name of the Fourth Book'"
