Introduction notebook outdated

[BorisVarbanov]

In the Introduction notebook the Setup is treated as a subscriptable object (and instead the contained dictionaries are now simply class members), resulting in TypeError erros. This occurs on cell 3, where the dictionaries are accessed (setup['qubit_dic']) and in cells 4,10,12 where the setup is incorrectly unpacked (**setup). @obriente

Fair point - the introduction notebook is now pretty much superseded by the QSoverlay tutorial notebook. Perhaps it's just better if I remove it.

Fixed already, I guess.
