/**
 * \class QSeisPageRegistry
 *
 * This class acts as a registry for all QSeisPlotPage
 * objects. This registry does not allow to (un)register
 * instances. Instead it creates a new instance if
 * getByName() with a non-existing name is called.
 *
 * The registry also passes the add/update/remove signals
 * to the PlotPage with the correct dataType string.
 *
 * On creating and destroying of an instance the
 * pageCreated/pageDeleted signal is emitted to keep the GUI
 * updated.
