//============================================================================
// Details: MI common code class. Command argument with addition options class.
//          For example --recurse 1 2 4 [group ...]. Arguments object that
//          require a list of options associated with them derive from the
//          CMICmdArgValListBase class. Additional options are also extracted
//          from
//          the command arguments text string.
//          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
//          options and so extract a values from it .
//          The CMICmdArgValBase objects are added to the derived argument
//          class's
//          container. The option arguments belong to that derived class and
//          will
//          be deleted that object goes out of scope.
//          Based on the Interpreter pattern.
