// .NAME vtkCPExodusIIInSituReader - Read an Exodus II file into data structures
// that map the raw arrays returned by the Exodus II library into a multi-block
// data set containing vtkUnstructuredGridBase subclasses.
//
// .SECTION Description
// This class can be used to import Exodus II files into VTK without repacking
// the data into the standard VTK memory layout, avoiding the cost of a deep
// copy.
