* @class vtkPExtractHistogram2D
* @brief compute a 2D histogram between two columns
* of an input vtkTable in parallel.
*
*
* This class does exactly the same this as vtkExtractHistogram2D,
* but does it in a multi-process environment. After each node
* computes their own local histograms, this class does an AllReduce
* that distributes the sum of all local histograms onto each node.
