public class GuardedObject extends Object implements Serializable
A GuardedObject encapsulates a target object and a Guard object,
such that access to the target object is possible
only if the Guard object allows it.
Once an object is encapsulated by a GuardedObject,
access to that object is controlled by the

checkGuard method on the Guard object that is
guarding access. If access is not allowed,
an exception is thrown.
