citizens/register

In the register controller(/api/v1/citizen/register), after registration and you 'citizen.save()', can you make it return a token just like it does in the login controller? The way it is now it seems, one would have to login again after registering.

you can make it something like:
```
await citizen.save();
const payload = {
id: citizen._id,
};
const token = jwt.sign(payload, mySecrete, { expiresIn: "1hr" });

res.json({
msg: "you are now logged in",
token,
});
```
