/**
*
* 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.
