/**
 * Abstract implementation of a ticket that handles all ticket state for
 * policies. Also incorporates properties common among all tickets. As this is
 * an abstract class, it cannnot be instanciated. It is recommended that
 * implementations of the Ticket interface extend the AbstractTicket as it
 * handles common functionality amongst different ticket types (such as state
 * updating).
 *
 * AbstractTicket does not provide a logger instance to
 * avoid instantiating many such Loggers at runtime (there will be many instances
 * of subclasses of AbstractTicket in a typical running CAS server).  Instead
 * subclasses should use static Logger instances.
