Triage of necessary node modules

[hepplerj]

I want to closely look through the current node modules in package.json and see what we can eliminate so we won't have to worry too much about dependency/security updates.

That's a good idea. There are basically three categories of dependencies:

• Visualizations
• Stuff for Foundation
• eslint

Maybe the Foundation stuff can go. They probably pull in the majority of other dependencies.

However, I think our security implications are low. We aren't running this JS server side.

This should also include removing any lingering gulp files, etc.
