* @class vtkNrrdReader
* @brief Read nrrd files file system
*
*
*
*
* @bug
* There are several limitations on what type of nrrd files we can read. This
* reader only supports nrrd files in raw, ascii and gzip format. Other encodings
* like hex will result in errors. When reading in detached headers, this only
* supports reading one file that is detached.
