; is directly density-reachable.
 A point q is directly density-reachable from point p if it is in the &epsilon;-neighborhood
 of this point.
 <p>
 Any point that is not density-reachable from a formed cluster is treated as noise, and
 will thus not be present in the result.
 <p>
 The algorithm requires two parameters:
 <ul>
   <li>eps: the distance that defines the &epsilon;-neighborhood of a point
   <li>minPoints: the minimum number of density-connected points required to form a cluster
 </ul></div>
