// An argument knows what type of argument it is and how it is to

// argument and so extract a value from it .
// The CMICmdArgValBase objects added to *this ListOfN container belong
// to this container and will be deleted when *this object goes out of
// scope.
// To parse arguments like 'thread-id ...' i.e. 1 10 12 13 ...
// If vbMandatory argument is true it takes on the (...)+ specification
// otherwise assumed to be (...)* specification.
// Based on the Interpreter pattern.
