//++ ============================================================================
// 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. This type having recognised its argument name just consumes
//          that argument or option (ignores it). This is the so the validation
//          process can then ask if all arguments or options have been recognised
//          other an error will occurred "argument not recognised". For example
//          this can be used to consume the "--" text which is not an argument in
//          itself. Normally the GetValue() function (in base class) would return
//          a value for the argument but is not the case for *this argument type
//          object.
//          Based on the Interpreter pattern.
