/**
* 
* CMCETestUIEngineAudioStream provides a wrapper for CMCEAudioStream.
* Class is not the traditional wrapper in a sense that it would 
* conform to interface provided by CMCESession. Instead class
* implements interface MMCETestUIEngineCmdProvider to provide
* same kind of functionality in controlled way on different levels 
* of abstraction.
