 * @class BrowserInterface browserinterface.h <KParts/BrowserInterface>
 *
 * @short The purpose of this interface is to allow a direct communication between
 * a KPart and the hosting browser shell (for example Konqueror) . A
 * shell implementing this interface can propagate it to embedded kpart
 * components by using the setBrowserInterface call of the part's
 * KParts::BrowserExtension object.
 *
 * This interface looks not very rich, but the main functionality is
 * implemented using the callMethod method for part->shell
 * communication and using Qt properties for allowing a part to
 * to explicitly query information from the shell.
 *
 * Konqueror in particular, as 'reference' implementation, provides
 * the following functionality through this interface:
 *
 * Qt properties:
 *   Q_PROPERTY( uint historyLength READ historyLength );
 *
 * Callable methods:
 *       void goHistory( int );
 *
