Need different visual indicators in the GUI for nodes and edges having multiple VNIs #52

Open dbooth-boston opened 8 years ago

Someone looking at the pipeline in the GUI needs to know that the component is splitting to multiple VNIDs, because they'll need to be joined later.

This is a general need: users need to be able to visually distinguish between nodes that have multiple VNIs vs nodes that only use the empty string vnid.

Also, vanilla NoFlo components do not propagate the vnid. This is not readily apparent in the GUI, which is error prone. It would be good to add both visual indicators of which nodes use multiple VNIs, and automated error detection if a multiple-VNIs node is connected to a single-VNI node without intervening split/join.

Ideally both the nodes and the wires should visually indicate that there really are multiple virtual sub-pipelines.
