* The #GdaSet object is a container for several values (as #GdaHolder objects). The list of #GdaHolder objects is
* publicly accessible (and should not be modified), using the "holders" attribute. Each #GdaSet object also
* maintains some publicly accessible information about the #GdaHolder objects, through the #GdaSetNode, #GdaSetSource and
* #GdaSetGroup structures (see gda_set_get_node(), gda_set_get_source() and gda_set_get_group()).
*
* It is possible to control the values a #GdaHolder can have in the #GdaSet by connecting to the
* <link linkend="GdaSet-before-holder-change">"before-holder-change"</link> signal.
