To enable printing of non-expanded samples I've shuffled a bunch of code
around and created a bunch of smaller routines to more easily support printing of both expanded and non-expanded counter and flow samples. I've done simple testing of non-expanded counter and flow, and expanded counter, but I don't have expanded flow at present with which to test. So, that part of the change is only compile/eyeball tested. Reviewed-and-tweaked-by: Guy Harris <guy@alum.mit.edu>
