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

// 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.
