//============================================================================
// 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.
