        Hi all

                [Sorry for the late reaction, I curently have an urgent 
situation which is swamping me]

                I have introduced a math folder but not a math namespace 
because I understood that was what the final recommendations called 
for. I can of course introduce the namespace math if it is deemed 
usefull.

                I personaly would like to introduce that namespace, as it 
could be a starting point to tidy-up and improve upon the existing math 
support (for instance one could then have templated trig functions...).

                I do not believe a quaternion or an octonion namespace is 
called for, but a special_functions might, however.

                The other point raised in that thread is a failure due to the 
instanciation of "sin(octonion<int> const &)" and such which may (or 
may not) be related to template-template parameters. I'll get a chance 
to work on that tomorow.

                At any rate, I believe these issues (and a few minor ones 
which cropped up) should be resolved before the libraries are 
integrated into a public release (by temporarily removing them from 
public access if need be).
