auth
auth/authcode.go
Create interfaces for login verification flow. We needed an interface that we could use to say "send the email to verify the user's login" so that we could verify the emails we have are actually valid. This implements an NSQ version that sends an email_verification event. We'll get listener implementations that pull these messages off NSQ and actually send the emails. This also implements, for testing purposes, a version that just echoes the Login Value and the Verification code to stdout.
