Code for testing the various jslibs.

`npm run test`

### Add a component to test:

For unit tests, add a `<component-name>.tests.js` under `src/tests`.  

Add the dependency using `npm install --save ../<component-name>` (using the folder feature of npm install, and assuming it's int the jslibs/ folder)

For viewing a react rendering, add to Add.js and run `npm run start`.
