Nearest neighbor search using a Uniform Grid.

Parallel search of nearesat neighbor for each point in the queryPoints in the set of coords. Returns neareast neighbot in nearestNeighborIds and distances to nearest neighbor in distances.

Parameters

queryPoint	Point coordinates to query for nearest neighbor.
nearestNeighborId	Neareast neighbor in the training dataset for each points in the test set
distance2	Squared distance between query points and their nearest neighbors.
