Go through my code. Use parameter node instead of getting nodes from the scene

[16djm10]

Instead of checking if a node type exists, check if the node ROLE is present in the parameter node. If it is not then save an empty node of that type to the parameter node

I should instead check if ROLE: connector is saved to the parameter node. If there is nothing with that role then I know to create one and save the ID to the parameter node.
