/*
Modified by: Mark Jenkinson (FMRIB Centre, University of Oxford, UK)
Date: July/August 2004
Mainly adding low-level IO and changing things to allow gzipped files
to be read and written
Full backwards compatability should have been maintained
Modified by: Rick Reynolds (SSCC/DIRP/NIMH, National Institutes of Health)
Date: December 2004
Modified and added many routines for I/O.
