	/**
	 * <p>The TuioServer class is the central TUIO protocol encoder component.
	 * In order to encode and send TUIO messages an instance of TuioServer needs to be created. The TuioServer instance then generates TUIO messages
	 * which are deliverered by the provided OSCSender. The shown UDPSender send OSC to UDP port 3333 on localhost or to the configured host and port.</p> 
	 * <p>During runtime the each frame is marked with the initFrame and commitFrame methods,
	 * while the currently present TuioObjects are managed by the server with ADD, UPDATE and REMOVE methods in analogy to the TuioClient's TuioListener interface.</p>
	 *<p>See the SimpleSimulator example project for further hints on how to use the TuioServer class and its various methods.
	 * <p><code>
	 * OscSender *sender = new UDPSender();</br>
	 * TuioServer *server = new TuioServer(sender);<br/>
	 * server->setSourceName("MyTuioSource"); // optional for TUIO 1.1<br/>
	 * ...<br/>
	 * server->initFrame(TuioTime::getSessionTime());<br/>
	 * TuioObject *tobj = server->addTuioObject(xpos,ypos,angle);<br/>
	 * TuioCursor *tcur = server->addTuiCursor(xpos,ypos);<br/>
	 * TuioBlob *tblb = server->addTuioBlob(xpos,ypos,angle,width,height, area);<br/>
	 * server->commitFrame();<br/>
	 * ...<br/>
	 * server->initFrame(TuioTime::getSessionTime());<br/>

	 * server->updateTuioCursor(tcur,xpos,ypos);<br/>
