 * <code>MvnForumGroupXML</code> class encapsulates processing of
 * groups' definitions found in the backup XML file. It implements
 * methods to be called from XML parsing routine, adds some additional
 * processing and checking, and calls corresponding methods of
 * <code>GroupXML</code> and other neccessary classes in order to perform
 * the actual creation of a group, as well as other related items (like
 * group members and group permissions). It also ensures that default
 * virtual <code>"Registered Members"</code> group is created, even if it
 * wasn't found in the XML.
