Input is a named vector of new fields. Use unnamed fields for comments. Quote field names with spaces (conventionally with back ticks). Note that this function will error out for invalid field names. See http://teem.sourceforge.net/nrrd/format.html for nrrd field details
Note that newfields should specify the complete replacement line as
a string (not the individual values for fields containing multiple
elements) without the leading field name (see examples).
