This notebook demonstrates how to check the usage of node definitions for node libraries.
The utility scans one or more libraries * Each definition is examined to see if it is implemented as a node graph. * If it is the list of nodes it uses is returned. * For each node that is used a list of node definitions that use it is returned. * A list of definitions which are not implemented as graphs as well as a list of nodes that are missing implementations are returned.
The utility also provides usage rate for node definitions and a hint of complexity of a node definition which uses other nodes by providing a count of the number of unique nodes it uses.
