I implemented mine years and years ago. Both linear and affine units. At 
the time, there were no template template parameters, and this made 
things awkward because I don't always want an underlying double (I often 
need a UDT) representing the number.

I've been very interested in these libraries, but so far they are all 
too physics-centric for my taste. Also, I've been totally overwhelmed, 
so I haven't had the time to look at your library at all.

I think I took a look at an earlier version and commented favorably on 
it, though.

If I ever find the time, I'll take a look and comment. If you dig 
through the boost archives, you'll find lots of comments by me about 
what I'm looking for.
