Maybe you can give the Tags (currentUser.getTags()) to the view, so
that the view is responsible for creating checkboxes or whatever, so
the presenter does not have to deal with widgets.
the view can map each Tab to the created Checkbox (to avoid the for-
loop) und call a method like tagChanged(Tag) in the presenter whenever
a checkbox is clicked
