Some antiretroviral code
Merge remote-tracking branch 'origin/master' into Steph-2.0
Antiretroviral functionality fully implemented

- at t-cell count of 500, prompts user if they want to take
antiretrovirals.
- if yes, increase t-cell count by 50 (# negotiable).
- Later will add functionality where it prints additional info to the
sidebar.
