** what a NrrdFormat can assume:
** -- that nio->format has been set to you already
** -- for read(): that nio->path has been set to the path of the file being
** read in, if the information was ever available
** -- for contentStartsLike() and read(): that nio->line contains the
** first line of of the file, in order to determine the file type
**
** what a NrrdFormat has to do:
** -- respect nio->skipData to whatever extent makes sense on top of how the
** NrrdEncoding respects it (by making read and write no-ops).
** nrrdFormatNRRD, for instance, won't create empty detached data files
** if nio->skipData.
** -- determine what NrrdEncoding to use, if there's a choice
** -- respect nrrdStateVerboseIO with messages to stderr, if possible
**
** The "unknown" format is intended as a template for writing new formats.
