/**
* Note on the layer mix with symbolic/ID-based interface:
* You create a new layer with
* pLayerAdmin->NewLayer("A new layer");
* This layer is automatically appended to the end of the list.
*
* The same holds true for layer sets.
*
* The interface for SdrLayerSet is based on LayerIDs. The app must get
* an ID for it at the SdrLayerAdmin, like so:
* SdrLayerID nLayerID=pLayerAdmin->GetLayerID("A new layer");
*
* If the layer cannot be found, SDRLAYER_NOTFOUND is returned.
* The methods with the ID interface usually handle that error in a
* meaningful way.
* If you not only got a name, but even a SdrLayer*, you can get the ID
* much faster via the layer directly.
*
* @param bInherited:
* TRUE If the layer/layer set cannot be found, we examine the parent layer admin,
* whether there's a corresponding definition
* FALSE We only search this layer admin
*
* Every page's layer admin has a parent layer admin (the model's). The model
* itself does not have a parent.
