Send the password to the user upon registration

When a user is successfully created, the auto-generated password should be either sent to users mobile (via a SMS) or the email.

- If a mobile no. is being passed in the request, and is successful, a SMS should be sent.
- If not, an email should be sent.

You must use IdeaMart API(s), for sending the SMS.
