 We can now define a class method named ==uniqueInstance==, as shown below. This method first checks whether ==uniqueInstance== has been initialized. If it has not, the method creates an instance and assigns it to the class instance variable ==uniqueInstance==. Finally the value of ==uniqueInstance== is returned. 
 Since ==uniqueInstance== is a class instance variable, this method can directly access it.
