/**
* MTag is the interface class for tag processing.
* A voice tag consists of a context, a RRD, and a speech item. A context can have
* multiple voice tags. Context represents the category (application) to which the tag
* belongs. RRD represents the result data for a tag. Speech item represents the speech
* speech data and speech activities for a tag. A client will not create a tag diectly,
* but use the methods in tag manager to get a tag. After getting a tag, the client can
* get the RRD and speech item objects using the following methods in MTag. A context needs
* to be created before creating a tag. After a tag is used, it needs to be deleted. Deleting
* a tag deletes its RRD and speech item, and thus they donot have to be deleted expicitly,
