This makes sure we use the codebase clone created for this experiment.
I.e. if you want to make modifications to the codebase but don't want your
running experiment code to be impacted by those changes, first copy the
codebase somewhere, and configure this section. It will make sure we import
from the right place.

MUST BE DONE BEFORE IMPORTING ANYTHING ELSE
(Leave this comment there so others will understand what's going on)
