Makes a deep copy of a list of nodes; corrects next,prev & parent references and then puts them into an array.

This is to detach nodes from their parent. Nodes are considered immutable, hence copy is needed.
i.e. Doing node.parent = null, during a traversal could cause traversal logic to behave unexpectedly.
