A local library needs a program that can manage data on the books that they have available. You choose to apply Object Oriented Programming techniques to design a class that can be used to store data on books. The library has indicated that the information they need to store are the following:

$1.$ The book title

$2.$ The book author$($s$)$

a$.$ Think about how multiple authors can be stored.

$3.$ The book publisher

$4.$ The book ISBN number

$5.$ The year the book was published

In addition, the library wants this system to track who checks in$/$out books at the library. The class should be able to store who has the book checked out currently, the date when it was checked out, when it is expected back. Additionally, if the book is overdue, $($I$.$e$.,$ still checked out after the expected return date$),$ the book class should calculate and return the overdue charges as of the current date.

Note that we are NOT writing the code for this class in this activity. Instead, you will create a UML table that expresses the design of this class. You will also describe the purpose of each class member $($attributes and methods$)$ in the same document. The UML table should be based on the table described in the slides on Object Oriented Programming.
