/**
 * \class QSeisCurveRegistry
 *
 * This class acts as a registry for all
 * currently available QSeisPlotCurves.
 *
 * The (un)registerInstance functions where
 * reimplemented to include the curveAdded/
 * Changed/Removed signals.
 * The QSeisPageRegistry relays on this
 * signals to maintain the existing list of
 * available curves.
 *
 * The resetRegistry() function is basically
 * the normal Registry::cleanup() function,
 * it only emits additionally the curveRemoved()
 * signal for every curve to keep the
 * PageRegistry on track.
