/**
* 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>
* <strong>IMPLEMENTATION NOTE</strong>: The <code>main()</code> method of
* this class is a simple example that exercizes the features of dynamically
* starting and stopping various components. You can execute this by executing
* the following steps (on a Unix platform):
* <pre>
* cd $CATALINA_HOME
* ./bin/catalina.sh embedded
* </pre>
