This class is meant to be used as a choice for the policy class RootPointPolicy of the CoverTree class.
This policy determines which point is used for the root node of the cover tree. This particular implementation simply chooses the first point in the dataset as the root. A more complex implementation might choose, for instance, the point with least maximum distance to other points (the closest to the "middle").
