// Details:	MI common code class. Command argument class. Arguments object
//			needing specialization derived from the CMICmdArgValBase class. 
//			An argument knows what type of argument it is and how it is to 
//			interpret the options (context) string to find and validate a matching 
//			argument and so extract a value from it. Thread group looks like
//			"i1" in the options text.
//			Based on the Interpreter pattern.
// Gotchas:	None.
