Node-Check Validation Component

This component checks whether or not a list of nodes is used in a given workflow.
It takes a workflow object and a table as inputs, then extracts information about the workflow in the form of a JSON file, and finally checks for the usage of the given node(s): in case of success, the data gets moved onto the component output.
The component is essentially divided into two parts: the "Extract Information" part, which encloses a recursive loop where information regarding the input workflow is gathered, and the "Node-Checking" part, which materially checks for the usage of the selected nodes.
It is possible to manually configure the component both by providing a list of nodes as input as well as by defining the degree regarding the depth of analysis.
