 * The extending point of basic JGSS-API.

 * If a module wants to extend basic JGSS-API classes, it should extends this
 * class and register itself as "the extender" using the setExtender method.
 * When various GSSManager.createXXX methods are called, they will call
 * "the extender"'s wrap methods to create objects of extended types
 * instead of basic types.
 * <p>
 * We have only one extension now defined in com.sun.security.jgss, and the
 * registering process is triggered in {@link GSSManagerImpl} by calling
 * Class.forName("com.sun.security.jgss.Extender"). Only GSSContext
 * and GSSCredential are extended now.
 * <p>
 * The setExtender method should be called before any JGSS call.
