Returns an ICENodeCollection containing all nodes
in this container, including both ICENode and the immediate ICECompoundNode objects. To access the
inner nodes of ICECompoundNode objects you need to call this
property on their respective ICECompoundNode parents (via ICENodeContainer.CompoundNodes).
This property is typically used for iterating over an entire node
graph. For example, start by calling this property on the ICETree. While iterating over the returned
collection, when you find a compound node, call ICENodeContainer.CompoundNodes
on it to get any inner compound nodes and so on recursively down
through the graph.
