/**********************************************************
 
CmdLineArgs2 is an extension of a map intended to map 
   qualifiers (e.g. -help) of a CLI to the index of 
   the argv[]. It's state is determined by a list of 
   ArgQual's/QualList. It then uses evalArgs to apply 
   those qualifiers to an argv[].
 
 - Qualifier -help is added in constructor
 - methods described in comments in definition
 
Example of Usage:
 
      Args2Container argsVec(thisProgram);
 
      QualList markers;
      markers.insert( make_pair("-somequal", ArgQual()) );
      markers["-somequal"].desc << "this is a qualifier with default=this";
 
      CmdLineArgs2 cmdLineArgs;
      cmdLineArgs.setArgQuals(markers);
      cmdLineArgs.evalArgs(argc,argv);
      argsVec.push_back(&cmdLineArgs);  // Add it to the list
 
      ...
