*		- Problem : when an event notification message is received and the message
*		            contains updates on more than one variable, only the first variable update
*		            is notified.
*		- Error :  the other xml nodes of the message are ignored
*		- Fix : add two methods to the NotifyRequest for extracting the property array
*                and modify the httpRequestRecieved method in ControlPoint
