Serialize a node to text in a NoOp node in Nuke. This could be helpful if some nodes of plugins etc. are causing problems on other machines like render slaves even if they are not connected in the node tree, but you also don't want to delete them.

serialize_node.py

# TODO:
# disconnect the SerializedNode completely
# set the position of the SerializedNode to the source node
# optional: after restoring the source node, reconnect all former inputs correctly
# (could be tricky when the script has changed in the meantime)
# optional: create the invisible node via python instead of pasting TCL code
