[boost] Domain library

To make the discussion of the Domain library a bit more concrete, I have posted a web page http://abies.nmsu.edu/software/domain/polynomial_library.html describing an example of using it to develop (a tiny part of) a polynomial library. For the moment it is a pretty raw page with broken links, etc. However, perhaps it will serve to give a better flavor of how this can be used to build other libraries. Even better, perhaps it will give a better opportunity for you to contribute new ideas that will improve the library. Thanks for your constructive feedback. Cheers, Brook
