Repo clean up (after week 4)

[azpoliak]

• src/:

  • Under src/ create a directory for each analysis method and move the corresponding python files there:

  • [x] topic-modeling

  • [x] `sentiment

  • [x] personas

  • get rid of imports.py and import python libraries that are necessary in each python file directly.

  • get rid of data files that shouldnt be here.

• data/

  • We'll clean this up later
