Multiple KML w/ Google Earth Plugin/API Limitation?

Question

So, I'm building a web application using the Google Earth Plugin and API. However, I'm running into an issue with trying to display more than one KML file; only the last file given loads up. I'm using the process KmlNetworkLink to display everything.

The desktop application allows this, so I'm not sure if this is just a limitation on the API or not. Does anyone know if this is a limitation?

Thanks in advance.

The documentation I am looking at: https://developers.google.com/earth/documentation/kml

EDIT: OP here. After working on this project for a few weeks, I've learned how to properly set up multiple KML tracks with the Google Earth plugin. I've revised my earlier answer (now shown below) to include a much cleaner and abstracted version of code. Hope this helps someone. Also (not listed here), it is possible store all of your KML locations in a single JSON and loop through it while calling createView() if needed.
