'''The variable empCount is a class variable whose value is shared among

all instances of a this class. This can be accessed as Employee.empCount

from inside the class or outside the class.

The first method __init__() is a special method, which is called

class constructor or initialization method that Python calls when you

create a new instance of this class.

You declare other class methods like normal functions with

the exception that the first argument to each method is self.

Python adds the self argument to the list for you; you do not need to include it when you call the methods.
