For classes that contain dynamically allocated data members, copy constructor and assignment operator should be implemented or both operations should be prohibited to avoid freeing freed memory caused by shallow copy. This commit declares both copy constructor and assignment operator as 'private' for classes that contain dynamically allocated data members. This will prevent freeing already freed memory.
