<p>Since <a href="https://github.com/mlpack/mlpack/pull/663" class="issue-link js-issue-link" data-url="https://github.com/mlpack/mlpack/issues/663" data-id="157761081" data-error-text="Failed to load issue title" data-permission-text="Issue title is private">#663</a> was accepted we have access to the projection tables of LSH. This allows for better testing. I added two tests for the current LSH implementation, and I will add more for Multiprobe on that branch.</p>

<p>The tests I have added project clusters of points on an orthogonal grid (of 1 or two dimensions) and then require that neighbors found don't contain any points of clusters that didn't merge.</p>

<p>I added a few comments here and there as well.</p>
