[boost] [graph] Disjoint Sets - the secret library

I was just comparing the library list on the website to the one in the repo, and I noticed 'disjoint sets' is listed on the website but not in 'libs/libraries.htm'. I think it either needs to added to 'libs/libraries.htm', or removed from the site. The header is in the 'pending' directory, and it doesn't seem to have been reviewed, so it looks like it should be removed from the site. It seems to be mainly used by the graph library, so maybe it could be subsumed by that? Also, the documentation isn't quite right as it says the header is at 'boost/disjoint_sets.hpp': http://www.boost.org/libs/disjoint_sets/ Does anyone have an opinion? (btw. I'm not suggesting removing the header, as that would break things) Daniel
