/*
Anmerkung zu den Layer - Gemischt symbolisch/ID-basierendes Interface
Einen neuen Layer macht man sich mit:
pLayerAdmin->NewLayer("Der neue Layer");
Der Layer wird dann automatisch an das Ende der Liste angehaengt.
Entsprechdes gilt fuer Layersets gleichermassen.
Das Interface am SdrLayerSet basiert auf LayerID's. Die App muss sich
dafuer am SdrLayerAdmin eine ID abholen:
SdrLayerID nLayerID=pLayerAdmin->GetLayerID("Der neue Layer");
Wird der Layer nicht gefunden, so liefert die Methode SDRLAYER_NOTFOUND
zurueck. Die Methoden mit ID-Interface fangen diesen Wert jedoch i.d.R
sinnvoll ab.
Hat man nicht nur den Namen, sondern gar einen SdrLayer*, so kann man
sich die ID natuerlich wesentlich schneller direkt vom Layer abholen.
bInherited:
TRUE: Wird der Layer/LayerSet nicht gefunden, so wird im Parent-LayerAdmin
nachgesehen, ob es dort einen entsprechende Definition gibt.
FALSE: Es wird nur dieser LayerAdmin durchsucht.
Jeder LayerAdmin einer Seite hat einen Parent-LayerAdmin, n?mlich den des
Model. Das Model selbst hat keinen Parent.
