// 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.
