Separate into 3 Notebooks - Issue 46

[greebie]

The title says it all.

This adds a domain, text and network notebook instead of the previous "all-in-one" approach.

I added some additional analysis to domains because it was too short.

This will be in draft until all the edits are done. Final commit will remove the larger notebook.

I pulled this out of draft mode for review. I kept the current larger notebook inside the repo and will remove it as the last commit upon completion of the review requests.
