Create-React-App for Plone-React

Create-React-App provides some convenience features, such as: a live development environment, boilerplate code, and standard dependencies pre-installed. The idea is to make Plone-react package as a dependency(library) to other packages and make ( use ) a create-react-app like app generator to generate the example boilerplate which fits with the package. By doing this it doesn't need to fork the repo everytime, just execute the command create-plone-react-app like so and we’ll be good to go.
