This script is run as the Apply event with the Click event of JUNCTION. It allows the user to click on those nodes which represent junctions with no ventilation. The OSBL portion of the naUTilus code assumes that every numbered node is a manhole unless specifically designated a junction with no manhole. The user is prompted from JUNCTION to select any nodes which represent closed junctions. These nodes are flagged in the node attribute table and a graphic (a red dot) is placed on the view at that node.
