/**
 * Convenience class to embed a Catalina servlet container environment
 * inside another application.  You must call the methods of this class in the
 * following order to ensure correct operation.
 *
 * <ul>
 * <li>Instantiate a new instance of this class.</li>
 * <li>Set the relevant properties of this object itself.  In particular,
 *     you will want to establish the default Logger to be used, as well
 *     as the default Realm if you are using container-managed security.</li>
 * <li>Call <code>createEngine()</code> to create an Engine object, and then
 *     call its property setters as desired.</li>
 * <li>Call <code>createHost()</code> to create at least one virtual Host
 *     associated with the newly created Engine, and then call its property
 *     setters as desired.  After you customize this Host, add it to the
 *     corresponding Engine with <code>engine.addChild(host)</code>.</li>
 * <li>Call <code>createContext()</code> to create at least one Context
 *     associated with each newly created Host, and then call its property
 *     setters as desired.  You <strong>SHOULD</strong> create a Context with
 *     a pathname equal to a zero-length string, which will be used to process
 *     all requests not mapped to some other Context.  After you customize
 *     this Context, add it to the corresponding Host with
 *     <code>host.addChild(context)</code>.</li>
 * <li>Call <code>addEngine()</code> to attach this Engine to the set of
 *     defined Engines for this object.</li>
 * <li>Call <code>createConnector()</code> to create at least one TCP/IP
 *     connector, and then call its property setters as desired.</li>
 * <li>Call <code>addConnector()</code> to attach this Connector to the set
 *     of defined Connectors for this object.  The added Connector will use
 *     the most recently added Engine to process its received requests.</li>
 * <li>Repeat the above series of steps as often as required (although there
 *     will typically be only one Engine instance created).</li>
 * <li>Call <code>start()</code> to initiate normal operations of all the
 *     attached components.</li>
 * </ul>
 *
 * After normal operations have begun, you can add and remove Connectors,
 * Engines, Hosts, and Contexts on the fly.  However, once you have removed
 * a particular component, it must be thrown away -- you can create a new one
 * with the same characteristics if you merely want to do a restart.
 * <p>
 * To initiate a normal shutdown, call the <code>stop()</code> method of
 * this object.
 * <p>
 * @see org.apache.catalina.startup.Catalina#main For a complete example
 * of how Tomcat is set up and launched as an Embedded application.
