Coupled Optimization Example Fails

Description

The example that is given in the Aviary Docs actually fails. We should fix this example so that users have something working to go off. This is probably one of the most important doc pages, as it highlights some of Aviary's most powerful features.

I rewrote a new optimization example from scratch in the documentation, which incorporates some ideas from that page! I will link this issue to that PR and close
