Set up emails

[lakesare]

Google: 'node, how to send emails', and research this topic. Choose the library to implement this with. Implement it :-)

Right now we do not send emails at all, - users don't get the email when they sign up, users don't get the email when someone joins their course, users don't get reminders for when to repeat their flashcards. All of this could be highly beneficial to users (one user wrote me she literally forgot the url and couldn't find memcode again!).

Hi Evgenia, I am Deepak Chakravarthy(KGISL),working on this issue. What is your opinion about using a 3rd party API for sending out mails. I am assuming we don't need an external inbox for tracking the mails.

I already have a working version of nodemailer in my local system. Thanks

@DeepakChakravarthy, hi! The external api is fine 👍

Update: emails were set up (thanks @DeepakChakravarthy), but now we need a system for rendering emails set up (can be another PR).
