Usage

You have to create the LOT instances with a user and a type (the uuid and the created date are auto-generated). Then you can use the lot login view, or the the lot login middleware. You can set the session_data attribute to add data to the user session when login with LOT.

If you use the lot middleware you can login in any url that have the param defined in the LOT_MIDDLEWARE_PARAM_NAME and have a valid LOT instance related to it.

If you use the view you can add the next param to redirect the user to an url after the login. By default will redirect you to the "/" url.
