// .NAME vtkAbstractPointLocator - abstract class to quickly locate points in 3-space
// .SECTION Description
// vtkAbstractPointLocator is an abstract spatial search object to quickly locate points
// in 3D. vtkAbstractPointLocator works by dividing a specified region of space into
// "rectangular" buckets, and then keeping a list of points that
// lie in each bucket. Typical operation involves giving a position in 3D
// and finding the closest point. The points are provided from the specified
// dataset input.
