On a NODE_MOVED event, the Map object returned by Event.getInfo() contains parameter

this event type: Session.move, Workspace.move and Node.orderBefore.
If the method that caused the NODE_MOVE event was a Session.move or Workspace.move then the
returned Map has keys srcAbsPath and destAbsPath with values corresponding to the parameters
passed to the move method, as specified in the Javadoc.
If the method that caused the NODE_MOVE event was a Node.orderBefore then the returned Map
has keys srcChildRelPath and destChildRelPath with values corresponding to the parameters
passed to the orderBefore method, as specified in the Javadoc.
