 * @class   vtkEnSightWriter
 * @brief   write vtk unstructured grid data as an EnSight file
 *
 * vtkEnSightWriter is a source object that writes binary
 * unstructured grid data files in EnSight format. See EnSight Manual for
 * format details
 *
 * @warning
 * Binary files written on one system may not be readable on other systems.
 * Be sure to specify the endian-ness of the file when reading it into EnSight
