+// 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.
+//			If *this argument has expected options following it the option objects
+//			created to hold each of those option's values belong to *this argument
+//			object and so are deleted when *this object goes out of scope.
+//			Based on the Interpreter pattern.
+// Gotchas:	None.
