* @class GCaldb
*
* @brief Calibration database class
*
* This class holds the definition of a calibration database. The
* calibration database is located in a root directory that can be set using
* the GCaldb::rootdir method. If no root directory is set, GCaldb will take
* the directory path from the CALDB environment variable, which is mandatory
* in case that no root directory has been set.
*
* It is assumed that the calibration data are found under
*
* $CALDB/data/<mission>[/<instrument>]
*
* and that the Calibration Index File (CIF) is located at
*
* $CALDB/data/<mission>[/<instrument>]/caldb.indx
*
* where \<mission\> is the name of the mission and \<instrument\> is the
* optional instrument name (all lower case). If the root directory has been
* set using the GCaldb::rootdir method, $CALDB is replaced by the root
* directory name.
*
* The calibration database for a given mission and instrument is opened
* using the open() method. Once opened, database information can be
* accessed. After usage, the database is closed using the close() method.
