Week 5: Class hierarchies/08. Write class SpecialDirector

+The program defines the class 'Director'. 
+Write the class 'SpecialDirector', which inherits the 'Director' class.
+
+The class must have a constructor that takes as parameters, 
+in this order, name, hours, overtime hours, and as a new parameter, special hours. 
+This parameter is also an integer.
+
+In the inheriting class, overwrite the method 'totalHours' so that it also counts special hours in the total number of hours.
