edu.internet2.middleware.grouper.*Save API's should have constructor/methods to set the session to use for the operation.

Please review all of the edu.internet2.middleware.grouper.*Save.java classes.

They all could use a constructor that passes in the session for the object to use.
*Save(GrouperSession session_to_use) {...}

These already support it, but not all of them do.
StemSave, GroupSave

Likewise the pattern of .assignRunAsRoot(boolean) would be good to also replicate to all of these classes.
