/**
* This class provides necessary Jingle Session jmf methods and behavior.
* <p/>
* The goal of this class is to provide a flexible way to make JingleManager control jmf streaming APIs without implement them.
* For instance you can implement a file transfer using java sockets or a VOIP Media Manager using JMF.
* You can implement many JingleMediaManager according to you necessity.
