This plugin provides a simple way to authenticate your users through Facebook's
OAuth API. It provides you with a helper to build easily a redirect to the
authentication URL, defines automatically a callback route handler and saves the
authenticated user to your session when done.
 
The authenticated user information will be available as a hash reference under
C<session('fb_user')>. You should probably associate the C<id> field to that
user, so you know which of your users just completed the login.
 
The information under C<fb_user> is returned by the current user's basic
endpoint, known on Facebook's API as C</me>. You should note that Facebook
has a habit of changing which fields are returned on that endpoint. To force
any particular fields, please use the C<fields> setting in your plugin
configuration as shown below.
 
Please refer to L<< Facebook's documentation | https://developers.facebook.com/docs/graph-api/reference/v4.0/user >>
for all available data.
