Problem

Github Issue Number: #123 The feature is not related to any problem but it's an extra feature that needs to be implemented. So the feature is if any user of the platform want to invite any other user which on the platform so they can invite through a link, which will be used by other to get registered as a user of the platform._

Solution of problem

One solution I can think of just generates the token using the senders token (use jsonwebtoken signed with the expiry time and sender's token). Now when the user who is invited will receive the link, let say: http://localhost:5000/invite/${token} and the link is clicked then a GET the request will be sent to the server so will catch that request and then in that request in the backend decode that token and check user collections if that user exists i.e sender and the token is not expired then it's valid invitation so now directly redirect the invitation receiver to the register page else send the message that invitation is not valid.
