       parsing, even though maptions is more elegant. reason: idea
       of rtInit(&argc,argv) etc is that they can take thoes options
       off the command line that they know, and return the rest to
       the app w/o the app ever actually seeing them. in particular,
       the kernel and the app should not use the same options class
       _instance_ (though they could of course use the same class to
       implement their behavior). to allow that, the options class
       would have to allow pulling parameters off, and returning a
       valid (though stripped) argc/argv to the caller.
       
       i.e., something like:
       
       //  while (myOptions.defined("res")) {
       //     FrameBuffer::options::defaultRes.x = myOptions.get("res", FrameBuffer::options::defaultRes.x, 0);
       //     FrameBuffer::options::defaultRes.y = myOptions.get("res", FrameBuffer::options::defaultRes.y, 1);
       //     myOptions.remove("res",2);
       //  }
