Logs out the specified Subject from the system.
<p/>
Note that most application developers should not call this method unless they have a good reason for doing

<code>{@link hunt.shiro.subject.Subject#logout Subject.logout()}</code>, not the
{@code SecurityManager} directly.

Framework developers on the other hand might find calling this method directly useful in certain cases.
