[jordanpadams]

Acceptance criteria:
Given the DOISearch component in the pds-wds-react, see documentation https://github.com/NASA-PDS/pds-wds-react#as-embeddable-js-doi-search
When I perform its integration in a web application non implementing React (pure html/javascript)
Then I expect To be able to integrate the component
Then I expect that the component works (e.g. for DOI search)

Figured out a good tool chain based off the work of this github project: https://github.com/jasan-s/react-embeddable-widget-starter. With just a couple of modifications and by adding in what we use we can create embeddable JS widgets.

I can confirm that React, Material-ui, React-router(hash router) and React-Redux code is built out. I tested this out and it works.

@eddiesarevalo will push the code to the pds-wds-web repository in branch. Until it can be merged with the existing code in this repository (the app bar).

@tloubrieu-jpl I created a separate branch in pds-wds-react to hold the toolchain setup. Once the npm library toolchain is created I'll merge them together and delete this branch.
