// 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. The print-values looks like:
//            0 or --no-values
//            1 or --all-values
//            2 or --simple-values
//          Based on the Interpreter pattern.
