Session handling with Firestore

A short App Engine app, which uses Firestore to serve a webpage saying "#{session['views']} views for #{session['greeting']}". Here, session["greeting"] is one of ["Hello World", "Hallo Welt", "Ciao Mondo", "Salut le Monde", "Hola Mundo"] which has been randomly assigned to the viewer, and session["views"] is the number of times that viewer has loaded the page.
To run, follow Ruby's Handling sessions with Cloud Firestore tutorial.
