       This module makes use of the CFITSIO module to read and write directly to a FITS HDU.

       It stores information about a FITS header block in an object. Takes an hash as an argument, with either
       an array reference pointing to an array of FITS header cards, or a filename, or (alternatively) and FITS
       identifier.

configure
           Reads a FITS header from a FITS HDU

             $header->configure( Cards => \@cards );
             $header->configure( fitsID => $ifits );
             $header->configure( File => $file );
             $header->configure( File => $file, ReadOnly => $bool );

           Accepts  an  FITS  identifier  or  a  filename.  If both fitsID and File keys exist, fitsID key takes
           priority.

           If "File" is specified, the file is normally opened in ReadWrite mode.  The "ReadOnly" argument takes
           a boolean value which determines whether the file is opened ReadOnly.

       writehdr
           Write a FITS header to a FITS file

             $header->writehdr( File => $file );
             $header->writehdr( fitsID => $ifits );

           Its accepts a FITS identifier or a filename. If both fitsID and File keys  exist,  fitsID  key  takes
           priority.

           Throws an exception (croaks) on error.

       Astro::FITS::Header::CFITSIO - Manipulates FITS headers from a FITS file

       This  module  requires  Pete  Ratzlaff's  Astro::FITS::CFITSIO  module,  and   William  Pence's "cfitsio"
       subroutine library (v2.1 or greater).
