*
* @brief Interface for FITS header class
*
* The FITS header class contains all cards that are found in the header of
* a HDU. All cards will be hold in memory, so no link to a FITS file is
* required. Cards may be read from one file (using the 'open' method) and
* saved into another file (using the 'save' method). Cards are added or
* changed using the 'update' method.
