<p>Yeah, I did a little reading and neither <a href="https://github.com/zoq" class="user-mention">@zoq</a> nor I can easily come up with a better solution, so I think this is the best way to go.  I added a little documentation in <a href="https://github.com/mlpack/mlpack/commit/7264d37128a9f97ee1f0d481f37cc2bf1d3b1f30" class="commit-link"><tt>7264d37</tt></a>.  Thanks for the contribution!</p>
