Added CLI init helper

[john-doherty]

Adding selenium-cucumber-js to a project is a bit of a hassle as you have to create the dependant folders. It would be far cleaner to execute two commands and have the framework up and running. For example

# install the framework
npm install --save-dev selenium-cucumber-js

# create folders and insert google example
node ./node_modules/selenium-cucumber-js/index init
