* Updates to match API changes
Update to the node to match the server API changes. An attempt has been made to leave a legacy path for existing installations that may have not updated the server side.
* Updated following comments.
Update following comments.
Output removed and node.warn or error used.
oneeditprepare added.
Name moved to last item.
In addition, a check added to ensure nodegroup has valid value.
Question: I have added a 'return' as I do not want data posted if there is not a valid nodegroup. Is this the best way to exit the function? Always taught that multiple exits was a bad idea. I wondered about raising an error / exception and then catching it but not sure how to do that.
* Update documentation for revised node
