[boost] Formal Review Request -- Interfaces

Hi, I would like to propose the proposed Boost Interfaces library, which I introduced several months ago, for formal review. (Or maybe I should say: I'd like to nominate the candidate Boost Interfaces library.) See http://www.kangaroologic.com/interfaces/ for download and documentation. The version to be reviewed will include a number of changes from the above version; in particular, about half of the features described in "Future Directions" will be implemented. However, the above version is self-contained and suitable for review, so I would like to propose it now and work on integrating the changes while it is sitting in the review queue. Jonathan
