stargazer not imported in this file prior to use

[joehcollins]

Just to let you know that stargazer is not imported in this file so the code will error at this line:

mixtape/python/collider_discrimination.py

Line 30 in 77e3de4

st = Stargazer((lm_1,lm_2,lm_3))

Seems fine in the other file in this chapter (chapter 3) which is movie_star.py.

(Really enjoying the book so far!! Thanks so much)

Thanks! We are updating the python files a lot right now, so this should be fixed :-)
