// .NAME vtkPComputeHistogram2DOutliers - extract outlier rows from
//  a vtkTable based on input 2D histograms, in parallel.
//
// .SECTION Description
//  This class does exactly the same this as vtkComputeHistogram2DOutliers,
//  but does it in a multi-process environment.  After each node
//  computes their own local outliers, class does an AllGather
//  that distributes the outliers to every node.  This could probably just
//  be a Gather onto the root node instead.
//
//  After this operation, the row selection will only contain local row ids,
//  since I'm not sure how to deal with distributed ids.
//
