[Cs3] copying in and out the stat of the object

[Mikhail Nesterenko]

CS3 students,

There was an, after class, question whether it is possible to copy the
state of an object in and out in inside a member function. We'll be
studying it later in the course. For the curious, this is discussed in
the "Memento Design Pattern" lecture and the corresponding example.

thanks,
