Firebase : Cloud functions with https trigger

Just running the quick start example seemed to be pretty easy. had to do the below in sequence

1. firebase login
2. firebase use --add from the app directory
3. npm install -g firebase-tools (i had this already installed, so skipped it)
4. cd functions && npm install; cd ..
5. firebase deploy

Done below was the output and hitting the url from browser shown the date.

mylap-MacBook-Pro:time-server mylap$ firebase deploy
