/**
* @class vtkNetCDFPOPReader
* @brief read NetCDF files
* .Author Joshua Wu 09.15.2009
*
* vtkNetCDFPOPReader is a source object that reads NetCDF files.
* It should be able to read most any NetCDF file that wants to output a
* rectilinear grid. The ordering of the variables is changed such that
* the NetCDF x, y, z directions correspond to the vtkRectilinearGrid
* z, y, x directions, respectively. The striding is done with
* respect to the vtkRectilinearGrid ordering. Additionally, the
* z coordinates of the vtkRectilinearGrid are negated so that the
* first slice/plane has the highest z-value and the last slice/plane
* has the lowest z-value.
