automation/unit test POC

Create a strategy for automation/unit tests per components

[chrismanciero]

@droshev - I started looking into unit testing components with Jest and Enzyme. I create a feature branch (https://github.com/SAP/fundamental-react/tree/unit-testing) which has my unit tests for the MultiInput component and SearchInput controls (both are now at 100% code coverage).

Running npm test:

Running npm test -- --coverage will give a code coverage report.

I removed the App.test.js file as well as configured the jest setting in the package.json file to only run the coverage report on the Components .js not on the .Component.js file since those files are the implementation of the components and I don't think are necessary to be tested.

@droshev @InnaAtanasova Should this story be closed since all components have unit test and we have the automated tests setup with the builds?
