// .NAME vtkParallelAMRUtilities -- Support for distributed AMR operations
//
// .SECTION Description
//  A concrete instance of vtkObject that employs a singleton design
//  pattern and implements functionality for AMR specific operations.

//  vtkOverlappingAMR, vtkAMRBox

  // Description:
  // This method detects and strips partially overlapping cells from a
  // given AMR dataset. If ghost layers are detected, they are removed and
  // new grid instances are created to represent the stripped
  // data-set otherwise, each block is shallow-copied.
  //
  // .SECTION Assumptions
  // 1) The ghosted AMR data must have complete metadata information.
