// .NAME vtkAMRStructuredPointsReader - read structured point data from AMR datafile.
// .SECTION Description
// vtkAMRStructuredPointsReader is a source object that reads AMR 
// data files. See text for format details.
// .SECTION Caveats
// Data stored in AMR format is binary (compact) and system independent.
// Information on AMR can be found at http://hdf.ncsa.uiuc.edu
// Information on HDFIO/IEEEIO can be found at http://bach.ncsa.uiuc.edu/IEEEIO
