/**
* @author foltin The original version was sent by Stephen Viles (sviles) https:
* group_id=7118 Initial Comment: The "New Parent Node" action creates a
* node as a parent of one or more selected nodes. If more than one node
* is selected, the selected nodes must all have the same parent -- this
* restriction is imposed to make the action easier to understand and to
* undo manually, and could potentially be removed when we get automated
* undo. The root node must not be one of the selected nodes. I find
* this action useful when I need to add an extra level of grouping in
* the middle of an existing hierarchy. It is quicker than adding a new
* node at the same level and then cutting-and-pasting the child nodes.
* The code simply performs these actions in sequence, after validating
* the selected nodes.
