ICECompoundNode

### Introduced

v7.0

### Description

The ICECompoundNode object represents a node sub-graph containing other ICENode objects such as ICECompoundNode and ICEDataProviderNode. An ICECompoundNode is like a basic ICENode with input and output ports. Note: ICETree objects cannot be part of a ICECompoundNode sub-graph.
