Login to GMQL REST services suite as a registered user, specifying username 
and password, or as guest, using the proper GMQL web service available 
on a remote server
If both username and password are missing, you will be logged as guest.
After login you will receive an authentication token.
As token remains valid on server (until the next login / registration or 
logout), a user can safely use a token for a previous session as a 
convenience; this token is saved in R Global environment to perform 
subsequent REST call even on complete R restart (if the environment has 
been saved). If error occurs, a specific error is printed
