There are two options: either a user can serialize an object or
deserialize it. (using the -s or -d flag). These options allow
for the demonstration of bidirection readability and writeability
between the original and the evolved class. In other words,
one can serialize an object here and deserialize it with the evolved
class or vice versa.
