+/**
+* 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,
