I don't understand the point here. Are you trying to make the
`approxNearestNeighbors` method completely private? There is still a public
overload of this method - which now shows up as the only method in the docs and
just says "overloaded method for approxNearestNeighbors". This doc above does
not show up.
As a general rule, we should always generate and closely inspect the docs
to make sure that they are what we intend and that they make sense from an end
user's perspective.
