I have doubts about this: see below.

There is a danger here of too many namespaces with no clear
cut division between them.
There is another problem: std isn't so factored.
Finally: I do not like having quaternions in one namespace,
and 'sin' in another, because it defeats Koenig lookup.
Instead of writing:
cout << sinh(q) << endl;
I'd be forced to write
cout << boost::math::special_functions::sinh(q) << endl;
or somehow bring 'sinh(quaternion)' into the current namespace.
[I'm not opposed to the factoring, just dubious]
