Part C: [20 pts] Write a class named LibraryEmployee. Each LibraryEmployee has the following attributes:

name: the name of the employee.

favorites: a set of this employees favorite Books (or ComicBooks).

num_coffees: an integer representing how many coffees this employee has had today. This value should begin at zero when a LibraryEmployee is initialized. The LibraryEmployee class should have an initializer that accepts the employees name and favorites as arguments. These values should be assigned to the objects respective attributes. Additionally, the LibraryEmployee class should have the following methods:

- drink_coffee(): takes in an integer num, and increases this LibraryEmployees num_coffees attribute by that integer.

- __str__() : return the LibraryEmployees name.
