Re: xdp2 nix refactor - fixed!

Woot woot!  I finally got the simple_parser working after updating the
xdp2 API and a few other changes

To debug this I added some "asserts" into the C++ code.  I wasn't
really sure the "best" way to do this, so I used the boost assert
stuff, given xdp2 already uses boost libraries.  Please let me know if
that sounds like a bad idea. :)

I'm also thinking I'll extract the embedded Python from the .cpp fils,
so that we can independently test the python, rather than getting the
python evaluation at compile time.  Should have zero functionality
impact.
