** AND NOTHING ELSE. See nrrd.h for why those fields, of all things
** are needed for {en/de}coding
**
** what a NrrdEncoding has to do:
** -- read data from file into the "data" argument (BUT NOT nrrd->data!!),
** or vice versa.
** -- respect nrrdStateVerboseIO with messages to stderr, if possible
** -- in case of error, put text error messages into biff via
** biffAddf(NRRD, <error char*> ...)
**
** The "unknown" encoding below is intended to serve as a template for
** any new encodings being developed.
