* @brief FITS file access class
*
* GFits is the basic FITS file interface. All FITS file handlings operate
* via members of GFits. A FITS file is composed of Header Data Units (HDU)
* which are implemented by the GFitsHDU class. Each HDU is composed of a
* header (GFitsHeader) and some data (GFitsData).
