Regarding sample rules from a Null or Loopback driver to use these classes?
There will be separate posting on how to use this jar with Loopback driver which is in progress.
Is there any chance of moving credentails from tree to tree with this toolkit?
yes, this can be done by iterating the each objects in the tree. Its not in the scope of this jar to move the credentials from tree to tree in a single shot.
Note: I have modified the description with more details.
