I have two range objects, and I want to subtract range B from range A. That
is, I want the opposite of Application.Intersect. This match concept is
illustrated at http://www.mathwords.com/s/set_subtraction.htm

I don't believe there's a single command for this, but can anyone provide
some thoughts? I plan on approaching this using a loop,
Application.Intersect, and Union() commands.

Thanks,
