I don't think removal would be the right solution, but it certainly
shouldn't be recommended as a best choice. Part of what I like about
this library is that it provides a framework for evaluating
comparative heap performance. While it doesn't appear to perform as
well now, it's possible that future architectures may be more amenable
to b-heap implementations. If not, then Boost has an implementation
that can be used to empirically demonstrate otherwise.

The same argument can probably be made for binomial heaps and fibonacci heaps.
