Welcoming users upon account creation

Welcoming our users when they create their account is something we would have definitely wanted to do before. But, due to lack of support, it was not possible. Now that we have this facility provided by Firebase, it allows us to have an extra custom backend to welcome users to account creation. In this recipe, we're going to see how we can make that happen!

      exports.sendEmailUponAccountCreation =     
        functions.auth.user().onCreate(ev => {
