The category path of this node in the graph item library.
This does not modify the node's title in the graph item library.
For example, if class A that inherits from Node has a NodeAttribute that sets its CategoryPath to "My Nodes/A",
then node A will have the path "My Nodes/A/A" inside the graph item library.
If you wish to modify the node's title, use NodeAttribute.Title.
