Detailed Description

A SdfLayerTree is an immutable tree structure representing a sublayer stack and its recursive structure.

Layers can have sublayers, which can in turn have sublayers of their own. Clients that want to represent that hierarchical structure in memory can build a SdfLayerTree for that purpose.

We use TfRefPtr<SdfLayerTree> as handles to LayerTrees, as a simple way to pass them around as immutable trees without worrying about lifetime.
