Create a parcel-story CLI

[yjose]

This is a simple issue to discuss some parcel-story cli specs.

• Is expected that the parcel-story cli can work in existing reactjs project and also for a new project.
• The parcel-story CLI will be based on the parceljs API, At this moment the parceljs API doesn't document yet (on the parceljs website) calling serve method to create a parceljs server development.
• We can use the serve function from Bundler https://github.com/parcel-bundler/parcel/blob/master/src/Bundler.js

Parcel-story CLI arguments (you can suggest more).

parcel-story init : To init a stories folders that export the index file. parcel-story or parcel-story start : To start the parceljs Hmr server.

read the readme file for more information about how the project works ! Any suggestion on how we can build the parcel-story cli ?
