FIXME added for unused logged_in variable for PEP8
FIXME added for unused logged_in variable for PEP8

The logged_in variable was being used but not
initialized. There is a commented out setting, and
also customer or context settings to choose from.

Commenting out the line since it is not useful now.
Adding FIXME because some unfinisted work is here.
