Done. It's under the spirit directory. Right now, I'm in the process of 
rewriting the core infrastructure. I am experimenting on making it more
MPL-like, with fusion::list, fusion::vector and fusion::vectorN. Also, while
looking at the current TR1 tuples implementation (at the very core), I
noticed that the comparison and tuple I/O operations are better implemented
with the algorithms (it was implemented by Jaakko before the algorithms
came into being). What's interesting is that you can do I/O (out) without even 
making a tuple-- just make a view.
