Display component links based on recommendation Plugin results. Closes #126

[umesh-timalsina]

Now that the recommended components are added to the circuit graph based on variable opacity, I think a workflow for this addition should be like:

1. Pass on a temporary node creation event to webGME, let the visualizer control create nodes and assign wires.
2. If no recommendation is taken by the user, remove the created nodes/wires.
3. If one of the recommendation is selected, remove the other two and let webGME handle the removal of nodes.

This will be nice to merge as it will make testing recommendation models (like https://github.com/symbench/electric-circuits/pull/120) easier. What is blocking it currently? Would it be possible to move the remaining tasks to a separate issue/PR?

[umesh-timalsina]

Sure. I will finish this up today. :)

Currently getting SPICE nodes from the plugin instead of GME Pin ids:
